Falldown is a relatively simple game in which the player controls a ball which falls indefinitely to the right. You control the ball by moving the joy stick up and down. You lose when the walls push your ball all the way to the left side of the screen. There is no way to win, you are just trying to get the high score. When you lose you move the joystick to the right to start the game over.
