Amazing amount of content for 3 hours, but since the mechanics are simple I guess adding so many levels was quite doable.
It has a unique charme to it and is certainly one of the more "complete games" in the jam.
Some feedback:
-Waiting for the gravity switch gets annoying quite fast.
- On player death you just reset the position, but the timer keeps on going - kinda undermines the rythm mechanic for me.
It's a little sad that you didn't make a browser-playable version - most people won't play it because of that :(
