It has the vibe I think you were going for. The bounce off walls doesn't do what is expected. Instead of reversing the velocity, you need to get the normal of the wall, and reflect the velocity around that.

I'm not sure I understood the objective of the game but it was satisfying to walk around with music :)

I really liked the gameplay and sounds, but the background was quite straining on my eyes. Overall, it's a successful game.
