The aim of the game is to keep the tennis ball bouncing for as long as you can.Use A to move the blue racket up and Z to move it down.Use M to move the red racket down and K to move it up.Press the arrow on the restart symbol to restart.
It took about 1 hour but it was realy easy.It was just because there was a lot of code.;D.Hope you enjoy!Also when you hit the top/bottom edge it will bounce for a while but eventually come out.
