you can defeat your opponent by bouncing on his head. Player 1(which has the red cooler in the game) can use the up arrow to jump, the left arrow to go left and the right arrow to go right.Player2 (which has the blue color in the game) can use key W to jump. Key A to get left and key D to get right. In the game you should also take note of some special power-ups, the blue is for slow down other player, the red is for extra life, the green for bigger jump, and the gray for invincibility. Look out for the player lives .you will failed if the lives get over.
