I think this genre and theme combination is my favorite so far, really enjoyed it.
Reusing movement to teleport blew my mind.
Really well done!
Just a feedback if you're going to develop this further.
I'd put the screen shake timed with the top beat indicator.
Not sure if I'm not getting it but it's hard to look at the "timing" at the top and at the movement down. If the screen shake happened when you're supposed to press movement keys you'd ease the puzzle mechanic and make it easier to enter the flow of the music/rhythm.
Don't get me wrong it's very much doable - and fun! - but way harder, found myself repeating a lot (reached 1-5)
Sorry for the long feedback, I really enjoyed the game.
Edit: I've read you received similar feedback about the indicator, maybe making it transparent over the center of the screen!
