Hello and thanks for the release,
I have found the map short and a bit annoying, sorry to say that, especially the switches part.
The battle lord used nearly all my ammo, but I blocked his sight, so he can't hit me. After that I found a secret near with plenty of ammo, a shotgun and a medkit (I used the map to check where there are enough room to put a secret) and no problem for the rest of the map. I have tried to get ride of bad guys with the gun trough windows and by taking cover, sometimes I shoot a passing recon until I get them all. With a less annoying switches part, it could be a cool secret level, as you mentioned. I still missed 3 secrets.
The design is clean but a bit tedious, just brown bricks and metal floor, I think even Doom have more variety in texture ^^. The use of the red palette for the sky is a good idea.
I hope you don't take this criticisms for just bashing, it's not my attention.
You have mentioned others doom map you have made, perhaps a link on the first post could be a good idea. If you have released them here, I'll try to find them anyway.
Just a last remark, there's a Trooper who shoot me trough a wall !
Bye and thanks again for the release.
