Move the cat around using the left and right arrow key to bounce the soccer ball around.
This started as an activity from Video Games: Design and Code Your Own Adventure by Kathy Ceceri 9781619303003. The book had really good background information and instructions to get started. Note: I modified the version in the book to bounce off of my sprite, rather than end the game. It was difficult to get a feel for how the sprite moved with the game ending so quickly. I also moved the sprite down by adjusting the Y coordinates. The sprite is better aligned with the background, which is also my own modification.
