Use the mouse OR the space bar. I recommend that you use space. I made it fast so it becomes harder. I got 31 on this myself. Pls note that the game has a bug that happens 5% of the time. If you get the bug pls stop and start again. Enjoy! *update: I HACKED the game and got crazy high scores by making the speed variable huge.
