Very enjoyable atmospheric game.
The only thing is maybe making the timing a bit more lenient as at the moment it feels quite strict. I liked the use of Gymnopedie No. 1 (i think?) as background music as it made the game less stressful and oddly relaxing to play.
A bit of polish to the player physics/collision and more variety to the mechanics would be good start for a longer post-jam version if you wanted to keep working on the game.
Overall, great game!
