Lesson ID 174: I can use IF ELSE statements within a game.

In this programming challenge you will use your knowledge of IF ELSE statements to create an interactive game. Your challenge is to design, build and test a game called 'Keep Up Challenge' in which a number of footballs must be kept bouncing by touching the mouse. If the ball touches the mouse, it must glide up to the top of the screen, but if it's not touching the mouse, it must head down to the ground.
