To control the red ball, use the arrow keys. To go up, use the up arrow, to go down, use the down arrow, to go left, use the left arrow, and to go right, use the right arrow. It will leave a changing color trail. (It starts over when you push the green flag.) BE SURE TO ALSO CHECK OUT PIXEL DRAW 2!
