Settings:

Player1: Moves with "A" and "D", jumps with "W".
Player2: Moves with "Left" and "Right" arrow keys, jumps with "Up" arrow key.

This is meant to be played in full screen and FHD resolution.

Rules:

Each player can hit the ball twice before passing it to the other player, if hitted three times the other player gets a point. The ball can hit the walls but not the ground. If the ball hits the ground another point is given. 

You can play by trying to beat each other or cooperate and try to reach your maximum volley points.

Have fun with this little piece of seal shit.
