Just completed your map on Ultra Violence, a bit rough in the visuals department but has some interesting combat encounters and was a fun experience. Especially like the ending where the lift is bringing you back to surface.

I like how the encounters either encourage enemy infighting or avoiding combat until you get the more powerful weapons at the beginning.  And when the game does give you weapons, it still tasks you with playing tactically to preserve ammo.

That said, I did notice a couple of missing textures, a strange bit collision detection in the lost souls room and unusual texture choices. Though the use of the slime texture as tree's at the exit got a chuckle out of me.

Just a side note if you make future Doom maps, it's generally assumed maps are designed with Vanilla Doom movement (No Looking Up or Down, No Jumping or Crouch) so if your map does require those more modern abilities, it would be worth mentioning if the map uses those abilities. I couldn't get the Rocket Launcher without jumping unless I missed something that lowers the platform slightly. 

Would be worth also mentioning what source ports you've tested the map with.

Otherwise, good job on the map!
