The idea is to bounce every falling ball back up by moving ur player sideways with the arrowkeys, and tilting with 'x' and 'z'. U earn points by getting the ball to bounce off the top of the opposing platform.
U lose points if the ball flies off the bottom of the screen. If ur score is negative at the end of a level u willnot proceed to the next level.
In the menu page u can also view the instructions by pressing 'i' and u can go back to the menu page by pressing the backspace.
