YOU MUST HAVE A USB VIDEO CAMERA TO USE THIS PROJECT. Click the green flag to start the game. Give Scratch permission to access your computer's webcam. You will see your image in the background of the program. When you smack the sprite, it will move in the direction smacked. It will move with a speed proportionate to how fast it was smacked and slow down as if by friction. To adjust the physics of this game, simply remix it!
