Fantastic concept. DDR, meets AMV, meets Warioware. Great animation style and choice.
The feedback I'd provide is that some sections (particularly the "jump" and "flying" ones) are mostly unintuitive. Small "jump gaps", can't jump before gaps to get a feel of the jump mechanic, strange hitbox. Made it feel like it was not actually physics based, but more like it was a "hit the button at the programmed second" type of gameplay.
But that's really the only major "negative" feed back I would provide, not a means to complain, but in case it's helpful for future ventures. This is still an absolutely fantastic little game that is well polished and insanely creative. Thank you for sharing it!
