The controls are too smooth, which makes it difficult. I suggest adding levels with platforms and more mechanics with a box.

I think the movement is a bit too floaty and imprecise, and sometimes I can't get onto some of the platforms because of it. You should also not be able to push the box out of the arena, because that happened to me one time.

The idea of playing as a bomb as actually pretty good though!

Cool concept, got hard very quickly! Was hard to move that box with the danger being so aggressive :D
