This is a really good game! It's a unique and interesting concept that I think was executed rather nicely in the form of a simple, yet surprisingly addictive game where the only control you need to know is "hold the screen, mouse, or spacebar to stop". The music does become a little maddening after a while (especially in the stages where the player will inevitably get stuck and frustrated trying to get out of), but overall has a nice rhythm and isn't overbearing.
My #1 problem with the game is definitely the fact that all the stages will lock when you refresh the page/leave the page and return to it. But at least the game is nice enough to keep your badges and highest score recorded for you (I am #3 at 09.9 seconds on the leaderboard as I write this). Overall a good game, and one that I think would work well as a mobile game/console game.
