A pretty unnerving game. I think the environment design is great, sound design is nearly perfect, the monster suitably disconcerting, and the level flow wonderfully strange. I have a few minor points as feedback. First is a technical point to make the font more legible. I understand the pixelated font looks better with the atmosphere of the game but it is incredibly difficult to read and when all context for the game comes from reading it should be less of a strain to make out. The other point of feedback I have is simply artistic preference -I don't think your monster needs the jump-scare string sting every time it is visible. It's presence and movements are already incredibly discomforting. The sound of it gnawing and moving is already skin-crawling.

I really enjoyed this and best of luck!
