This is a simple pong clone based on my Game Frame framework. http://scratch.mit.edu/projects/38327246 The right paddle can be moved with the mouse. Remix me! Try adding different costumes for the paddles (shorter ones) for different levels when certain scores are reached. You can also change the speed of the ball. As pointed out in the comments the "AI" isn't very good. make a better one! The Game Frame also has levelup and winner, and loser messages. Add screens or animations for those.
You'll note that the formula for bouncing is different when bouncing off the top and bottom, versus the paddles. Can you explain why this is? Hint: what direction is the ball travelling? Is this motion natural? Can you make it better?
