Try to keep the ball from hitting the bottom. The paddle or bat (whatever you want to call it) will follow your "mouse pointer" and that is what you can block with. Good luck!
Thanks to Usborne's "Coding for Beginners using SCRATCH" book! And of course, the classic Pong from the equally classic Atari. Should I make a two player version? The only reason this is not two player, is because I didn't have another person to play player two, and so (of course) one player could play it. Something completely random: Do you have an Atari that works? I do... Not totally random...
