The game
Send the ball over the net and make it land on your opponent's side to win a point. The first player to 6 points wins.
You can hit the ball as many times as you like, and you can win a point even when you didn't serve.
Play a friend in two-player mode, or take on a lineup of computer opponents in one-player mode — where you're the slime on the left.
One player — you control the left slime
