App Description: This is a game that involves a ball in the center of a square. Each side of the square is a different color (red, green, blue, or yellow). The ball also changes colors (red, green, blue, or yellow). When you press "Start", the ball will change to a random color and move towards one side of the square. Whichever side of the square you tap, the ball will move in that direction. You must tap the side of the square that is the same color as the ball. If the ball hits the side of the square that is the same color as the ball itself, you will get a point, and the ball will change colors randomly again and move in another direction towards a side of the square. The speed at which the ball moves increases as you score more points, so the difficulty gets progressively harder. See how many points you can get! When you are satisfied with your high score, you can submit to the Game Center leaderboards if you wish, to see how you stack up against others.
