Move with the arrow keys. The more points you have, the worse you're doing. There's a light blue moon-like thing in the corner. If you get to it, you win. Basically, you want the lowest amount of points and the lowest time as possible, but don't rush. If you get stuck at the top, you have to move all the way back to the upper-right hand corner. The spinning line will also mess you up if you touch it.
