Very cool Ideas. At first I was confused as how it fits into the theme but then the rythym change the scale too. I felt like this game is way too hard though. It may be do-able but I'd rather it be easier at start and get harder.
I also think the jump is a bit annoying as it is soo floaty.
I discover some bug with the ui, the level 3 and 4 is exactly the same with the only different being the pitch of the sound in the level
after I finish stage 5 I presses next stage and it goes back to stage 4.
overall very interesting concept with polishment and good level design this is a very potential game.
