Ok, played it through, and it was a fun, back-to-basics oldschool ZDoom map. There are some problems however:
Ammo placement is a bit dodgy, but the amount is fine.
The monsters really need to be deaf or something, as setting off the entire map just by punching that ettin wall is not good, as they run around all over the place and make some parts very hard, and tend to get lost, making the killing of the entirity of the monsters to be very hard.
The fog choices seemed a little odd in places, particularly some eye-gouging lilac under one of the lava pools!
The demons in the lave pools weren't a good idea, as they made dying in the lava harder rather than easier.
There's some missing textures on one of the doors into the cage with the revenants, imps and demons on the way to that teleporter (that takes you into that tower in the middle of the lava pool).
There's a few too many shoot-activated doors, when really they look like they should be press-doors.
The map has lots of places that are easy to miss... not sure if that's intentional or not.
Looks a little odd in places due to lack of texture alignments, though I think the general look of the map is pretty good.
You seem to put a load of powerups in one place... but it's very easy to go there last because it's not the most obvious of places to go.
Level progression was very random. I didn't have a clue what I was doing until I had pretty much cleared the map out, then I found the exit all of a sudden.
The switch to the exit room is located in a room, with a door that only lets you in once... might want to reconsider that.
And for some extra praise - I really liked the forest bit. The look and gameplay there really stood out in that map.
Overall, it's pretty good, but has several minor flaws in it. Sod all the complaints you'll get about detail (or the lack thereof), oldschool is great.
