I usually try to reward players that like exploring and going into every nook and cranny. I've hidden ammo and health in secrets or just parts of the map that most players don't bother going to the first time around - usually it involves jumping or going behind some crate. I've tested all the maps before release and it is beatable without any secrets - although you're going to have to make the shots count, on UV. I can assure you that if you got to the secrets, you'll have more than enough ammo to kill every single monster and still have a substantial extra for the next map in line.
@Graf:
I can't help myself! D: I have an obsessive-compulsive personality that if I see something wrong with anything I did, I'm compelled to to "fix" it. But you're right, I have never finished a projects - that includes things outside of Doom-modding as well. That said, regards to DE, it's mostly due to my ambitions greatly exceeding my skills when I started on the project. When I dropped the overblown Episode 3 idea, my new goal was just to make a mod that was on-par with Doom quality. But my artistic skills have only recently started to catch up to that, and now real-life issues have caught up.
@Jimmy:
The roadblock is the sprites and graphics. No sprites of what I need exists in the current resource pool for Doom, nor do my older stuff measure up to Doom's quality. As an artist, it's easiest for me to point out flaws in the graphics and this most of my scrutiny are placed there. I'm honestly thinking about just focusing on the graphics portion and asking for a few people to join me for the maps and stuff. It doesn't help that my recent PC crash somehow managed to corrupt BOTH of my external hard drives. Not really sure how that happened, but half the graphics files have the upper half of it look fine, but then the lower half either lost all the colors, is inverted, missing sections, or parts of another file pasted into it. Although I've extensively backed-up my files on CDs and on-line, I still lost 1 rotation for my Draugr sprite (which amounts to like 1 week), some work on my Hell Duke, and 1 1/2 maps, which was a remake of the newer Episode 2 map, and another one I recently just started.
