You need to make sure the ball does not touch the blue line. If the ball touches the paddle, it will bounce. To see ping game, Version 2, go to https://scratch.mit.edu/projects/575515974 . If the ball touches the line, Your lives will change by -1. If you have 0 lives, the ball will say ,"You loose!" and the game ends.
I would like to thank my CCA teachers for giving me the instructions to make this game.
