The item sprites could do with transparent backgrounds instead of just being square images, the idea is quite nice, but i dont really see it being too chaotic in nature. The sprites are pretty good and the mechanics do what they are supposed to. The music is a little offputting, it's just a tad too "in your face" i guess is the best way to describe it, it's a little too punchy, i feel like this game needs something more akin to slightly energetic elevator music.
Other then those complaints, the game is great!
Keep up the great work! :)
