The gravity marble is not mine. i only created about 60% of the entire script. the rest came from the "Gravity marble" file that came with Scratch. Hold space to use pen. Arrow keys to move. Left and right arrow keys also change the pen color. Use numbers 0-9 to change how fast the marble moves towards you and away from you. Sometimes, the marble gets stuck on the walls. If it does, just click the green flag again.
