In 'Ball Pain', you control a small red ball which falls downwards due to gravity. There are randomly generated upward rising platforms which prevent the ball reaching the floor, where the game will then be ended. However, if the ball stays on a platform for too long, it will hit he ceiling and the game will again be over. The more movement left and right will increase the score, however dropping down using the down key decreases the score.
LEFT Key - Moves the ball left. RIGHT Key - Moves the ball right. UP Key - Bounces the ball. DOWN - Drops the ball downwards through the platforms. ENTER - Restarts the game.
