I really enjoyed your ambient and monster sound effects. Mechanically you made some clever decisions, showing me where the keys were felt too trivial at first, but after dying once I knew I had to lock in - the pinwheels really screwed me dude haha.
Your good mechanical awareness has been hampered by the seeming lack of artstyle a little bit, not the worst thing in the world, gameplay is king afterall , but even something small like sticking to a limited set of colours from a predefined, cohesive colour palette online might go a long way. Try the website Lospec for colour palettes, its usually for pixel art and not 3D, but for a game with albedo only textures theres nothing wrong with that.
All in all I had an entertaining 4 runs, thanks for the experience :)
