I liked the controls. Being able to move downward quickly by pressing down midair was a nice touch. I think the double jump should not start if you've just kept your finger down from the first jump. (I press and hold the jump key to jump once, but I end up double jumping). I would suggest adding an invisible wall on the left side of the screen so the player doesn't run off screen, out of view. Fun game, the giant beatboxer looked pretty cool too!
Bug . The speed of the beats grows to impossible levels the longer you play (every new game, the speed is increased. I just closed and reopened the game to fix)
I played many attempts until I went back to beat1 and this was the result of the bug
