I suck at rhythm games, but I was still pretty excited to see one here. I'm kinda surprised there aren't more of them given the modifier. The concept and aesthetic are a great fit for the jam.
Unfortunately, there's a lot of little flaws that take away from the experience. Missing notes doesn't seem to have an audible effect. The notes are in one corner of the screen, so you can't really see any of the action that it's supposed to be linked to. The end of the song isn't the end of the level. The difficulty ramp on the fourth (third?) level is insane.
It also didn't seem quite synced, but there are a lot of factors potentially at play so it might not have been the game's fault.
