Interesting concept! My main nitpick would be that the beginning of the game felt a bit slow. I only really started getting into it as the speed began to pick up and jumping over the boxes was more of a challenge. You could mitigate this by introducing the controls/multiple dimensions here or even giving players an option to speed up (at their own risk.)
Besides that, I really liked the music, visuals and the overall atmosphere of the game. You did a fantastic job and I think with a bit more tinkering you could make this a really fun game!
