Can you beat the hardest game? Use the arrow keys to move up and down but the horizontal movement is out of your control. In order to pass the levels you must collide with every pink square before exiting through the doorway to the right of the screen. Since you are constantly moving you must guide your character so that it bounces off the squares in such a way that you touch them all. Be careful not to touch the sides or the green shapes or it will b the end of you! The levels will become increasingly hard as you progress. Good luck!
