To move the penguin across the screen, use the arrow keys or the buttons on the side to move, and to throw snowballs at the polar bears, use the space key or the button in the middle. The objective is to remove all the polar bears at the top of the screen, while avoiding the ice blocks they throw at you. If you get hit, you lose. Once you have removed all of the polar bears from the screen, the game progresses to the next level.
