I like it. In my opinion the music you selected fits perfectly with your game.
As others pointed out, it seems that sometimes it took a while to a glitch to appear and that could be a little frustrating.
I reached level 3 and nothing happened, I assume the game ends there. Would be nice to have a way to communicate that in order to be clear, just a simple end screen would be great to make sure it looks finished and not a bug.
