This is unlike any rhythm game I've ever played. I wouldn't call it a platformer-rhythm mashup, more like a rhythm-puzzle game. You have to figure out how to move your character to be at the right place at the right time. The element of timing is less important, but it's a good tradeoff for the concept. I would really like a hit sound for the notes, in most of the songs I feel like you're meant to hit them on the offbeat so that would help you feel connected with the music.
The biggest flaw I see is the difficulty. That is, I'm not even sure it's humanly possible to hit all notes, aka doing an FC, on all levels. The first level is the only level where I can kind of understand how it would be possible, the others just seem impossible to me. If they're not impossible, I'd say the game fails to teach you the mechanics properly.
In conclusion, I liked the music, the graphics are clean, and there are some brilliant ideas being used, but the execution could be better. Basically, give it some polish!
