The program involves a game of tag where both sprites have different attributes. At the beginning of the game, the speed of each sprite is asked for the user to enter The cat gains speed by moving vertically, and loses speed by moving horizontally. The mouse gains speed every time it's touched by the cat. The mouse yells "OH NOO!!" when it's caught. My personalizations include: It changes the background every time a character is touched. The speed the mouse gains is 3 instead of 5 when touched. Each sprite makes a noise when it's touched.
