Liked this one a lot, really challenging! There's a definite sense of dread at the very start, when I see the room but can't see any monsters yet. You can tell it's about to get bad but you aren't sure how, and that's a great feeling.
The final room feels like some great catharsis, mopping up the Mancubi and Barons with rockets after the rest of the level was a real challenge.
My only real criticism is that the elevator into the final room was a little frustrating- I had to reach the top and then the Mancubus would block my progress, so the elevator would go back down, and I had to wait for it to go up and down a few times before I was able to actually step into the last room. That was the only issue though!
- Additionally; I loved the little visual touch on the computer console in the first room, with the small sectors torn out and a fire/lava texture on them. That was a really cool detail I would never have thought of :)
