Press the flag to start. Select your difficulty (1 for easy, 2 for normal, 3 for hard and 4 for extreme) Move the mouse up and down to control the left paddle which is yours.
NOTE: I belive difficulty 3 (hard) is probbably the most clumsiest, so is probbably easier. But Extreme difficulty feels the hardest with quicker reaction times on the computer paddle and also faster ball travel speed.
