As a fellow unreal-using, dank room-making, PC-heating developer - your game was pretty nice!
The atmosphere is good although at times pretty dark. I wasn't sure what killed me a few times. Jumping over tripwire was a bit weird considering I couldn't see my legs, but the game was forgiving enough. I also saw no use in picking up items, except that one skull (you know the one ;) ). After I went through the final door the game started looping and I spent the rest of my days in the dungeon. . .
Anyways, it's very good for a first attempt
