Loved the art! It creates a nice little underwater horror ambience that matches the audio very well.
Two points of feedback (acknowledging that this may already be on your backlog given limited game jam time):
1. It'd be nice to have an audio or visual feedback indicating when you enter the next room. I kept hovering over the top of the room and kept touching the entrance collider without noticing it was changing rooms.
2. There is a bug where you get stuck on the sides of the map and can't move if you press up and down.
Excellent entry overall!
