This game has apples falling randomly from the top, and you must use the left-and-right arrow keys to make the Cat Sprite catch the apples. If you are successful, your score increases by 1. If the apple falls all the way to the bottom, your score decreases by 1. You can also vary the speed of the game by using the "game_speed" slider between 1 (slowest) and 5 (fastest), and the game calculates the time between clones as a random number between 1 and "game_speed" divided by 5 (an inverse relationship, so that at the fastest setting, there is only one second between clones, and at the slowest setting there is anywhere between 1 and 5 seconds between clones).
