pretty good! i love rhythm games and thats a good one!
Sometimes it seems a little out of sync but its okay
the idea is promising, the game's art is a little disappointing because of the cover but it's okay. during the gameplay there is an infinite ladder that if you find it you don't need to do anything else to win and after you die the game continues running without you, it needs a mechanism to restart when you die. Keep working on it, it's a good start.
