Try to kick the sushi roll as often as possible into the goal of the opponent sumo fighter. The faster you shoot a goal, the more points you get, but the more goals you shoot, the better the computer sumo fighter will play.
If the ball is close to your goal, just run into your goal pressing the grab key (key [up] or [W]). If the ball is not yet behind the goal line, it will roll over your sumo. Then jump right (without grab key) to shoot the ball to the right. The gameplay remind us of the slim games and is very inspired from the slime soccer game.
