I absolutely loved this game. It was a fun experience and I hope there are more procedurally generated hells to explore in the future.
The biggest issue I had was with footstep sounds. I think it's really important for a game that relies on ambience to have proper material specific sounds, like in the end with carpet vs orange tiles, or with the puddles in the beginning and even the start of the game with pavement and grass.
I look forward to more :)
