Use arrow keys for player 1, and WASD for player 2. Press space to get a rainbow ball. WARNING!!! DO NOT PRESS SPACE IF YOU HAVE EPILIPSY! Can someone fix the meatball getting stuck in everything? Feel free to remix.
I made 1 player Paddleball, and thought "Why don't I make a 2 player game?" Check it out over here: https://scratch.mit.edu/projects/165876049/ The song is called Megaman.
