Click the pen down button to make the sprite stamp, press the space button to stop the stamping....I'll add a clear button soon but for now just click the flag again:P It might take a while for the whole effect to come together but it'll look like it's defying gravity by climbing the back round.
It's nothing like the original project. I know, I know I should of just made a second project but I just didn't feel like it:3. But the original project is cool so you should LOOK at it!:)
