The atmosphere is impeccable. The clinking of stone. The splash of water. The soft creaking of bone. The shadows of corpses appearing behind your path, a portent of what's to come. It's fantastic.
Unfortunately, I didn't find anything. I ended up getting super lost and found neither the exit nor doom. I know the exit exists, other people have found it, but I simply wore out my patience.
All-in-all, good work!
