Use WASD and the arrow keys if you are doing two player, and just the arrow keys if you are doing only one player.
INSTRUCTIONS: Use the arrow keys to race your marble around the track to the finish line. If you slide off onto the grass, it will slow you down. What's your best lap time? If you want to play with another person, press the "g" key. If you don't want to anymore, press the "h" key. HOW IT WORKS: The marble has variables for its x and y velocities. The arrow keys make it accelerate by changing the velocities. The grass slows you down by multiplying the velocities by a fraction.
