Great game, brings out my inner masochist (in a hard-but-fair way). The power ups look really cool, how did you make them? Like geometry dash it makes you play along to the music. I'd say it's even fairer than geometry dash. It's also the right amount of hard for only 2 levels.
The only bug is that if you jump at the right time the spikes desynch from the music and you can just walk over them. One way you could fix this is when the player reaches a certain angle around the planet (say 45 degrees) You could disable the controls and use Vector3.Lerp(playerPosition, destination, Time.deltaTime) to move the player over a fixed time period.
Anyway yeah, made me swear, good aesthetic. Great game guys.
