The music and visuals are nice! I love the jumping they do.
I was able to make it up to third level. The input required felt too complex for me at that point.
It is worth considering using one key for each item (hold to pull and release to smash) Also preferably keys which are somewhat close to each other on QWERTY layout (last I checked, most people use this layout)
Btw what was the reasoning for choosing the input keys that are set now?
