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).
This game uses the "create clone" and "when I start as a clone" blocks to generate clones of the Apple sprite at random horizontal locations along the top of the stage, and having them fall at random rates. Possible enhancements: 1) Adding a "You Lose" condition when your score goes negative 2) Adding a "You Win" condition when the score reaches some maximum value (like 50). 3) Adding a sound when the Apple falls all the way to the bottom 4) Adding other types of fruits or foods that are good to catch (i.e., score a point) 5) Adding other non-edible falling objects that need to be avoided (i.e. lose a point or quit the game) 7) Make the falling rate of the objects be based on the "game_speed" setting, to increase the overall complexity of the game
