[Community Project] 20 Monsters Challenge [RELEASED!]

[Jigstraw]

Map 19 didn't even work for me. Two posts back someone mentioned something about a zero gravity room? If it was the spherical room with 4 cacos, mine was broken. I finally managed to actually kill all the cacos, and then couldn't get out of the room. Had to use noclip to collect the key and move on.

[NAG]

Now, the 5 worst maps...again in no order...oh boy.
Map 17 by NAG. Visually, this map is awesome but sadly it's not well balanced in terms of gameplay. This is easily the hardest map of this megawad.

Thank you for the feedback. It's hard for me to get the difficulty level right, because I usually play on lower difficulties myself, and I'm never sure how hard people want UV to be. I definitely used too many cacodemons as well.

Believe it or not, the editors actually made my map easier than it was on submission! They were more generous with pickups, and they removed a timer that barely gave you enough time to run from the hidden switch in the air vents to the rocket launcher in the cave. In retrospect, I should have made that switch more obvious.

[Accensus]

Ooooh so that is how you access the RL? Neat. I don't know how much time you put on the switch, but I doubt it was enough with all the action going on.

As for the bug on MAP19, I never managed to reproduce it. It once happened to me, but that's about it. Thought it was fixed. Hm.

[kadu522]

Regarding maps i find the one from kinsie the most ridiculus.

WHY HAVE SELF-REVIVING ENEMYS FOR NO RESSON!!!

[Jigstraw]

Heh, if it helps, I'm not on the absolute newest GZDoom I don't think. 2.3pre-343-g49605bc. haven't needed to update for any particular reason in awhile but I figure if anything causes issues with wads it's probably my version of gzdoom.

[leodoom85]

I did a playthrough, even uploaded it. And it was in GZDoom 2.2.0

[DavidN]

Finally got a chance to try this - it's great to see the ways that people work with the 20-monster restriction I've started putting together thoughts at http://teamouse.net/games/doom/d20m.txt , having played through the first 16 maps so far... I can see what people mean about 17, it's definitely a tough one.

---

MAP01 - The Beginning by leodoom85

Nice alternative techbase style, well suited to being MAP01! I like the use of the silver accents to break up the green textures. Monsters were appropriately placed, not too challenging but enough to have the terrain advantage sometimes. And always check behind you for the chainsaw

MAP02 - Ambush Facility by Lil'Devil

Hah, nice surprise at the start - and the ambushes keep coming very creatively! Seeing a large crate room was a bit offputting, but it didn't last long and I liked the gag of the lone crate inexplicably stuck to the ceiling Great theme and execution.

MAP03 - To Hell and Back by Caligari87

Again, nice theme The door to hell looks a bit weird, the texture being too wide for its thin sector. The yellow door is nice but the skulls at the sides don't look or behave like switches! And I was about to say that this was the first map where I didn't actually find all the monsters... but of course that wasn't the end! Good fake exit, though I thought the map seemed like it ran out of monsters a bit early, with the path after the fake exit completely open. But great contrast between the two areas and well-realized theme!

MAP04 - Underglow by Nevander

Spectacular aesthetic - tonight we rave in hell! I love the use of the tracks of moving coloured lights. Again, it feels like you used up all the enemies too early - they're all out of the way by the time you even see the first key, and then it's just a matter of going back through the map opening the doors to reach the rainbow stairway to the exit. Looks absolutely great, though

MAP05 - Wrong Destination by ZioMcCall

Could also be called "Wrong Direction", the intro graphic and text disagree on this one.

Oop, chaingunners right off the bat. At least there's cover if you're careful. I think that the doors being flush with the walls instead of recessed a little by another sector makes them look a bit weird - there's also an odd problem with the roof on the stairs/ramp leading up to the upper level which you only notice if you turn around (missing upper textures, maybe?) and nothing really happens on the upper area apart from picking up bonuses. The secret is super-obvious, too Nice sudden change of scenery behind the red door, though - that was a good contrast. And overall, the variety in scenery in the map was good!

MAP06 - Polarity by Jimmy

And now we're in space! This is a really interesting take on the idea, especially as most of the monsters are untouchable at first - that allows the map to be a lot bigger than a 20-monster map normally would be. The scenery's great, liked the idea of the secret rewarding you with a crusher for the central cacodemon. I'm not a great fan of instant deaths in the main room, but as this one means you've fallen off and been lost in space forever I suppose it makes sense. I completely ran out of ammo at the end and resorted to just running away.

MAP07 - Arena by Lud

A 20-monster arena - I expected to breeze through this! But the hitscanners being on a timer mean that you really have to move quickly or you'll be overwhelmed. When the cacodemons appeared it actually got a lot easier, because they got in the way of the chaingunners a bit and weren't as effective from a distance. So nice work pulling off an arena map with such restrictions, and setting it to that music from Unreal Tournament

MAP08 - The Entrance by isaacpop23

Interesting little map with a mini-challenge behind each door, but none of them quite match up to the surprise of the first! Nice idea waking up the Cacodemon with the cracks in the ground that are normally used as just part of the scenery.

MAP09 - Crimes by Kinsie

Hah When I was in the ZZT community I made a game called "ZZT Crime" which demonstrated all the cliches or annoying things new people did in their maps - meaningless big piles of monsters, pointless twisting paths... this would be a good analogue of it for Doom The map has a great repeating pattern, a combination of hilarity and dread as the next obstacle is revealed. I'm just glad you didn't plonk down twenty thousand Cyberdemons at the end.

MAP10 - Abandoned Depot by Mor'ladim

Spooktastic opening The anticipation as you walk through the suspiciously empty corridors and rooms is incredible, building up to that first encounter - you elicited a "...fuck me" from me playing in the dark at 11pm after my baby daughter had been successfully put to sleep The arena at the end feels a bit out of place given the theme of scares, but by that point I was very glad to have a section of the map that didn't frighten me to bits.

MAP11 - Ghosts of Mars by Vostyok

And we're back to Doom after a brief trip to Resident Evil! This is a nice compact map with good scenery, comprising corridors around an outdoor section - though the rooms all feel a bit cramped. There's also no obvious reason the exit door can't be opened, it looks like a regular door!

MAP12 - The Warehouse by Voltcom9

Nice use of custom textures to give a dingier, industrial look! The heavy use of 3D floors gave the map a more vertical component that I liked as well. I know having all but one of the twenty monsters as chaingunners was a deliberate thematic choice, but I think it made the map a lot more homogenous and... boring than it otherwise would have been.

MAP13 - UAC Station by BillGuy

Agh, I swear I know this music from somewhere. Anyway - great scenery, nice touch putting the exit in a place where it's frustratingly visible from the start. The situation you force the player into shortly after starting is great, having to dodge the chaingunners while dealing with the demons. Then... I got a bit stuck, eventually realizing that I was meant to straferun over to the red key... is that really the intended solution or did I miss something obvious? Nevertheless, great architecture throughout and a nice change of scenery to outdoors halfway through - with some well hidden secrets.

MAP14 - Treacherous Library by FishyClockwork

Okay, I know that the moment I shoot anything this room's going to come to life and - oh my god what is happening. Great map that does the unexpected at every turn, reminiscent of Tricks and Traps but going even further - nice detailing of hell showing through in places. I tried the red key route first, setting the tone of what was to come quite nicely - I was actually surprised, after that, that the yellow route was a little tamer, I was expecting a second move from the skulls/bones room. And was I meant to know the combination to the blue room, or just brute-force it like I did? After that, I should have seen the final trap coming

MAP15 - Cratered by Tapwave

Another nice darker map... in fact, it was too dark on my monitor and hard to see where I was going! The atmosphere is good, though - having to swim in from underwater and grab the key from an out-of-the-way base. I didn't find any of the secrets on this map, but I did spot the red skull lying just out of reach...

MAP16 - The Mean Streets by Zero X. Diamond

Nice job rendering cars in the Doom engine This city map has a lot of work put into it with the custom textures and everything and I like the crumbled roads - the human locations make it look more Duke Nukem than Doom. It feels a bit big for a map that was restricted to twenty monsters, but it means that it doesn't outstay its welcome and that all your objectives are clear (three open buildings, you need three keys - no wandering around stuck for hours).

[Accensus]

Hey, good stuff, man! Thanks for the reviews, DavidN! Certainly good to hear feedback, and it's twice as better if the feedback's positive.

Also, the music in BillGuy's MAP13 is custom. It's unlikely that you've heard exactly that one. He's made it himself. Good track, indeed! One of my favs in the project.

[BillGuy]

Hey DavidN,

Thanks for taking the time to write short reviews of each map, that's really helpful to see what others think and what troubles they have. To answer your question, yes, strafe running was intended for reaching the red key on MAP13. The confusion was my fault for not broadcasting that, I'll do better in that regards next time - good job in figuring it out!

[DavidN]

You're welcome! I think that was the first map I've played where straferunning was an intended mechanic, so I'm not sure how to effectively indicate it's intended Great music, by the way!

Added some more thoughts up to MAP25:

---

MAP17 - The Cauldron by NAG

Blimey. As others have said, this map definitely stands out as the hardest by a mile - I've been playing these through on UV and I was on the point of just IDKFA-ing through it and declaring the map impossible. But determination got the better of me, and I finally bested it - I'm not sure if this is the intention, but it's more like a puzzle map, having to work out how best to use your limited resources against the overwhelming opposition. The route that worked for me was to get the shotgun from sergeants behind the right-hand door, to then deal with the chaingunners in the far door and to lure the Cacodemons up by hanging around a bit. Then backtrack through the vents to the room with the ammunition and go up the lift instead of down to get the chainsaw from the secret - the Cacodemon is easier to deal with that way. After getting the chainsaw, dealing with the cacodemons in the rooms with the walkways becomes easier - and leaves you ammunition to get rid of the last ones in the final room. (I never found the way to open the rocket launcher, but that would have been nice.) So... I think the map is far more difficult than it should be and that the Cacodemons act as irritating meat shields if you play it straight, but it ended up being very satisfying (and exhausting) when I finally reached the end.

MAP18 - The Abandoned Mine Shaft by SoulCircle

First, a word to Lud for connecting these two maps together quite so appropriately The music is... completely unsuited for the setting but also absolutely epic! The map goes through three different environments - two are abstract and hellish, and one is darker and more human... of the three, I actually liked the first area the most. The torn door in the third area was nice, although having such a vast area visible can look a bit plain without a lot of work in detailing. Gameplay is also very straightforward with only one branch off the main path - but as an experimental map this shows promise

MAP19 - Want a Piece of Me by UnTrustable

The general construction of the level as this island in lava is nice - the layout could have been a bit less linear, it's rare to encounter a door that you haven't already picked up the key for in the preceding encounter. The part with the 3D floor and the chaingunners has the player backtracking a long way along a boring corridor with no traps - contrast that to when you pick up the blue key, which is a good moment that catches the player off guard!

The low-gravity egg room is a fun idea, but I think you crammed it with too many Cacodemons - they can block the player in and have too much health to be able to create an escape route quickly. And I don't think the "kill all enemies to leave" mechanic adds much - the player will have done that already by the time they reach the exit because of the level's linearity.

MAP20 - Lava Pits by Gothic

Nice late Doom2-like scenery here The start feels like you don't have quite enough ammunition, and is a little reliant on finding the chainsaw secret (which was a nice touch that was more Quake-like than Doom - in fact, the same goes for the lowering platform with the red key). The instant death lava was a nasty surprise - while it makes sense that you'd just melt if you tried to run across lava, it's a change to Doom expectations that can leave a player bewildered when they try to dash across a tiny channel and suddenly lose the level. It might have been better if you'd moved a couple of enemies at the start to the end, giving the player a bit more challenge in the last building - but it's a pleasant map overall!

MAP21 - The Wicked Sepulchre by Zero X. Diamond

Speaking of Quake-like stylings. Nice moody texturing - I wasn't a great fan of the crusher maze, finding it a bit too frantic especially when trying to go around corners. But I got there in the end and was impressed that the pit led directly to a new area and not to a teleport like I think most people would have done. You're given very little time to get all the way across to cover with a ton of hitscan enemies shooting at you... and the trap when you think you've finished it all is nasty but well sprung

MAP22 - Up by UnTrustable

A map with a couple of curious gimmicks! I initially thought that the ascent through the cylinder was going to be the whole map and was sort of disappointed when it wasn't - but the other set-pieces were interesting as well. I'm impressed that you managed to stack so many doors directly on top of each other in the stairwell, but that section is a long stretch of being handed supplies that you don't really need - I've complained a bit about too many Cacodemons recently, but this could actually have done with more powerful enemies instead of grunts that you can chainsaw your way through easily. The last room was the best, with the rising slime that you needed to use to get to the top of the room while staying clear of it - I'd have liked to see that idea expanded into a multi-level room like the last ones were.

MAP23 - UAC Research Facilities by Titan314

Nice detailing in what would otherwise be a simple corridor at the start, it sets the level up well. The red key feels pointless, being right across from the door it opens - and deeper in the base, there's no pattern to which doors you can open and which you can't, some visible damage or blockade on the ones that don't open would have been nice. After some great-looking corridors and rooms in the rest of the map, the crate room felt awfully generic, especially sandwiched between the rest of the map and the well-done final teleport room. But apart from a couple of lapses, this is a good-looking and fun map

MAP24 - Doomja Vu by Luigi2600

Genuinely not sure why the map is called that! I was expecting a mashup of familiar levels or previous rooms, but I didn't find anything like that. What's there is decent, though - good attempts to vary the wall textures early on, though the later rooms are very bland by comparison. Having something change on the way back from the red key would have been good, to surprise the player and justify that rocket launcher.

MAP25 - Tremors by Vostyok

Now THIS is doomja vu - the starting corridor and room are very reminiscent of Quake's Necropolis! The feel of the map is also Quake-like in general, especially the secrets which need you to notice things and experiment with them instead of just finding hidden doors. Architecture and monster placement here are both great - I liked the crusher that gave you just, just enough time to work out what was going on. Sending three cacodemons the player's way at the end was the only bland-feeling thing, but overall this was a fantastic map.

[DavidN]

Spent a while away from this, but here are the next ten - there are some real highlights in here.

---

MAP26 - Metropolis of Ashes by Deviluke Roy / unRyker

I like the setting here - definitely a visually nice map! It seemed rather easy but think I made the map a lot easier for myself by following the EXIT signs first and finding the ammunition in the secret behind the skin wall (which was a bit obvious). The arena felt a bit big for having such a small number of monsters, but it was good that you saved a couple of demons for the journey back at the end (they seemed to be placed quite far out of the way, though, and are easily skippable). My only real problem, though, was that the switch to get the yellow key was unnecessarily non-obvious - but nice trap after finding it

MAP27 - Bloodbath by Janus3003

Oh, a bloodbath The secret was good but perhaps a little easy. I can tell the cracks must have taken a while. The SHAWN corridor with the steps up was a bit weird and plain, and the fight with the cacodemons in the dark room was dull because everyone is completely bottlenecked and you can only fight them one on one - I think it would have been better to let the player get into the room first and then spring some enemies on them. But nice concept for a map!

MAP28 - The Crucible by Voltcom9

This will be the deadliest game of snooker ever. Great architecture in a more traditionally Doomy way than your other map in this pack, but I recognize the affinity for 3D floors And the atmosphere is fantastic - the timed release of the shotgunner made me jump, and you used the small number of enemies really well, making them feel really oppressive even in ones or twos. The use of lighting to point the player in the right direction is a nice touch.

I knew that there was no way in hell that was going to be the exit - but the rockets "secret" behind it was a nice reward for the wary

MAP29 - Castle Chaos by Crazy Toni

I love maps that take place in multiple realities - surely a difficult task in this challenge where you had to divide the monsters between the two of them! I'm not a great fan of the 3D stairs - I think they would have looked better cut into the wall, but their positioning allowed you to reveal the downward stairs. A couple of other points I found weird - the red keycard is given out very easily without a challenge to get it, and it's usually inadvisible to use the SW2 switch textures because it confuses the player as to which switches have been pulled and which haven't. But I want to give special mention to the boss fight, which was completely unexpected - what a great little piece of scripting to achieve the transformation

MAP30 - Woeful Hills by unRyker

Great architecture once again, as I'd expect from a map with this name attached I wasn't sure about the crushing corridor - I found the radiation suit secret but was then compelled to rush the rest of the level before it ran out in case it would come in useful later. The other secret isn't very secret, but is very much appreciated Is that sky from the Rise of the Triad intro?

And then I stepped through the door into a Doom 1 techbase with much more basic architecture - I thought the effect was pretty jarring, even though it was deliberate. I was very confused at the big pile of items but obligingly wandered into the trap Good music, too.

MAP31 - Jigoku

Well, I suppose we're in hell now. Great foreboding and oppressive atmosphere - the columns are disorienting (in a good way!), and then in the main part of the level you feel appropriately slightly underpowered against the monsters that are closing in. (Until I remembered about the chainsaw, which helped.) I thought the secret at the bottom of the big water pool was great, somewhere the player wouldn't think to look (except me when I skilfully fell into it by accident) but the blue key underwater in the next room kind of gives the game away. However, by that time it's less useful, so I don't know.

I also didn't realize I was supposed to die to end the level! Although having nowhere else to go makes it obvious, I naturally avoided the painful floor at first.

MAP32 - Hell Crypt by Dr Pypsy

A nice tribute to E3M1! The map architecture is a bit plain in places but it all works, and I liked the bait and switch on the red key. I would have liked to have some kind of clue as to which path to take on the causeway rather than a 3x3 grid of just guessing (but let me know if I'm stupid and just missed the clue).

MAP33 - Kill-o-Seum by Sgt. Shivers

I laughed at the name I chose to go for a stealthy approach here to dodge around to the switch, which worked great until I was perforated by chaingunners. Then I stayed in the corridors on the edge of the circle and it was a lot easier - perhaps too much of a workaround, really, but it's up to the player whether they want to be cowardly like me or not. Otherwise, nice mini-arena map - and the secret was cleverly hidden!

MAP34 - Spawning Grounds by BillGuy

I thought this might be the same author as MAP13 just by looking at it Looks great and complex right from the start. Interesting and clever approach to keep the player mostly underpowered and running away until later in the map when they get the weaponry to deal with the monsters - the Berserk pack in the secret helps a lot. (Er, then I tried the map again and noticed the shotgun that had been right in front of my nose from the start - but I wanted to keep that last comment in to acknowledge that the map works like that, too.) The architecture is really good and the map feels tight and streamlined.

MAP35 - Celestial Abominations by FishyClockwork

Interesting map with a lot of use of unusual elements! I'm not sure I've seen a hurting wall before. I'm also not sure why I walked into it quite so enthusiastically. The room with the rotating switch and the fireball traps kind of reminded me of old PC RPGs like Eye of the Beholder, and the grated floors going out into space give an unsettling unstable feel.

I wondered at the start of this venture whether people would use more physical traps in place of monsters, and this one definitely goes in that direction - in fact the physical puzzles were so much a part of the map you barely needed the monsters! Great use of scripting and atmosphere to give a more Hexen-like feel. I'm not sure how much this will mean to most of the board, but it made me wonder how well a game inspired by Knightmare would work in ZDoom.

[Accensus]

Oooooh! New episode! New episode! *grabs popcorn*

Thanks for all the reviews, man!

[Vostyok]

Nice! I really like reading these.

As an aside, Doomja Vu did actually include portions from another map (not sure which, you'll have to ask the playtesters) justifying the name, but it was judged by the moderating team as plagiarism. Generally, unless the mapping is done completely by the author (i.e. not copypaste), radically different, or "tongue-in-cheek" as they say, it is generally frowned upon, and I'm pretty sure /idgames have a specific rule against that sort of thing.

Also, Knightmare Doom needs to be a thing. I remember living near some kid who won the "eye-shield", and wanted to go over there at some point and rob him. Ah, the ambitions of youth....

[DavidN]

Aha, that makes sense... I understand why the change had to be made. And wow, that's a major celebrity you grew up near as far as I'm concerned I've felt for ages that the technology is there to recreate it, with Youtube and VR and everything, but nobody has! "Keep Talking and Nobody Explodes" is kind of close, with one player giving instructions and one doing the actions...

I tried out playing Doom Knightmare-style once. We should really have turned the vertical aiming off, though. https://www.youtube.com/watch?v=dJ29d2FMGkI

Anyway - here are the rest Thanks to everyone for a great team project!

---

MAP36 - Unexpected Turn by leodoom85

This is a curious one - the red rock corridor is long but has a lot of out-of-bounds scenery that stops it from becoming monotonous. The encounters at the end of them are good in their own ways, but the wooden-themed one was a little hard to spot. The map definitely had at least two unexpected turns, but the first one confused me - I wasn't sure why, after an effect I thought would teleport me or otherwise affect the map dramatically, I was being prompted to go back and knock out the Cacodemons in the same places. I was expecting the map to have changed more, but I can understand why it didn't given the time constraints. I even took a look at the script to see if I was missing something - I didn't identify anything, but I can at least comment that using loops would make your life a lot easier

I was wondering when someone was going to surprise me with a custom boss! (Or irritate me by putting a Cyberdemon in that I have to fight with my fists). This boss was a nice touch, I found it a lot easier the second time when I'd worked out the rhythm but the first time was a moment of panic.

MAP37 - Sacrifices by BillGuy

Hi again A different map style from the two bases, but I still recognize the affinity for ceiling detail! The player starts off in a bad place here and has to run for cover before things really kick off. This is another more physically-themed map, making it able to be longer despite the monster limitation, and it has a good variety of different challenges to collect the three keys - I love how the monster restriction spurred people into finding other ways to be creative. I adored the effect of the spiral staircases building themselves

I think one gravestone would have been enough in the hunt - I found the one to open the cage first and was then confused when I couldn't jump up to get the key or fit around the altar to get it from the other side! I also think the jumping (well, more like sliding, with Doom anti-jump restrictions) sequence was a bit much and could have done with being a bit shorter.

MAP38 - Ascend Beyond Hell by leodoom85

It's 3-3 between the top two mappers now, who's going to emerge with more? My habit of checking behind me finally paid off here, not many maps have rewarded me with that instinct so far. This is another script-heavy map like the end of Unexpected Turn, and its position in the map sequence makes it feel like something big is coming The central mechanic works well and it breaks its own rules just as they're becoming routine (which is great!), though I think that leaving the surprise up to the player would have been better than printing the protagonist's thoughts on the screen. Great out-of-bounds scenery again, though - I only found two of the four secrets and feel that I'm missing something quite big

MAP39 - The Idol Who Twists Mortal Minds by lwks

Re: the automap - hey, same to you!

This map kept me guessing - I knew there was something weird about the environment and the large space with few monsters gave me a sense of foreboding... but the twist still surprised me - well done I think it's possible to get stuck in the "upside down" section if you go through the blue door again and teleport back into it, but it's possible that I just didn't remember the way out. Nevertheless, I IDCLIPped across the void. Something weird happened to the inside of the three-key door when it was fully closed and I'm not sure if it was a result of that: http://i.imgur.com/UqR7F0L.png

MAP40 - Symbols of the Demon by BillGuy, leodoom85, Tapwave AND Lud!

A supergroup to complete the WAD And it has a very oppressive atmosphere with the lava everywhere and new scenery - very fitting for the deepest level of hell. I wasn't sure how I felt about the damaging floor in the ring around the outside, as it seemed to slow the pace down to a crawl with you having to step or jump carefully over to avoid taking too much damage - I'm also pretty certain that I missed the teleporting line somehow the first time around.

FFFFFFFffffffuck me. Please don't do that, I'm on anti-anxiety pills as it is and you caused me to swear quite violently in front of my visiting mum :X But with that out the way, the arena battle at the end felt suitably climactic - the anti-Cacodemons making a reappearance from MAP36 tie the levels together well, and their twitchy, too-fast movement gives an uncomfortably oppressive otherworldly taste to them. Great effects on the cracks appearing on the seal, as well - I was expecting something a bit different the second time instead of another wave of them!

MAP41 - Where Nazis Belong

I utterly failed to find the route to this level. Nevertheless, nice little Wolfenstein 3D environment, especially starting off in the prison where it's very much a tribute to the original map - and rather better-looking than the one that ID Software did, using the giant textures more appropriately in a Doom 2-like setting Found the secret route after a bit! Undecided about how I feel about it - do I play Doom to distract myself from the fact that that mangled hellfruit is the leader of America? Yes. Does he deserve to be mocked mercilessly at every possible avenue until his head eventually just bursts? Very much.

MAP42 - 2 Minutes to Midnight

Excellent alternative style of map to use as a secret, a sort of blend of Rise of the Triad and Total Wipeout I haven't tried it in co-op but the setup for it looks great! I was absolutely useless at the jumping over the platforms between the fast burning pillars, and I thought that the puzzle bit in the middle brought the pace down too much, but the race against the voodoo doll was particularly inspired

And finally...

MAP00 - Credits

What a great touch at the end Thank you to all the mappers and everyone who contributed to this project - and the organizers did great work in tying together a disparate set of maps by very different authors! I keep on saying that I'd love to participate or organize one of these eventually, and some time I'll manage it...

[Tapwave]

I only found two of the four secrets and feel that I'm missing something quite big

Stuff blowing up. Look carefully everywhere.

Something weird happened to the inside of the three-key door when it was fully closed and I'm not sure if it was a result of that: http://i.imgur.com/UqR7F0L.png

GODDAMNIT I SWEAR I HAD FIXED THIS

I utterly failed to find the route to this level.

My first map. Be a vandal.
