I'm pretty sure I made it to the last level, but the level counter reset to 1 around 9 or 10. The movement was a bit weird at first, but it actually works quite well.
Oh yea, that's a bug, the level counter can't show more than 2 numbers. There are actually 12 total levels, once you finish them all, you will get the credits screen so you'll know when you finished the game.
