Use arrow keys to direct pen.There is a new version of this. It's better graphics. Press "B" to switch color to blue, "Y" for yellow, "G" for green, "P" for purple, "O" for orange, and yeah. If you want to switch back to black, press "B" and the "2". Press "0" to auto-draw a slinky, "5" to auto-draw a pentagon, "9" for a star, "3" for a triangle, "4" for a flower, "6" for a hexagon, and "8" for a octagon!
My Scratch camp! Sorry, graphics may look bad in full screen.
