Gravity will pull everything towards the earth. They haven't really explained the phenomenon, but they know that it exists. In the game Gravity Ball, gravity is both your enemy and your best friend. If you use it wisely, you can succeed and score mega points, but if you let it take ahold of you, then you will most certainly die. Use the arrow keys to manipulate the ball. Gravity is in effect, so be careful in how long you hold any one key. If you touch any of the walls, you will die. Have fun, because this game is a blast!
