Use WASD to move the sprite. Click 1 when your ready for the yellow ball to chase you. Its speed will increase after it touches you. Click 1 to start the game after you are tagged. At the beginning input your speed and the sprite speed for the game. To personalize the game I added in both a game mode where you run away from the sprite and where you chase the sprite. I also added in my own backdrop and had fluent controls for x and y rather than the choppy moving spaces. Having ball sprites also add to the fluid movements. The sprites where also balls rather than a cat and mouse. Whenever you get tagged a popping noise plays.
