Press the green flag, then hit the spacebar or use the right arrow key. The blue outline means to draw that part first, then the red. Ok, I'm no artist in any way so if I can do this, you definitely can. Also, when I actually draw this on paper, things look a lot better, so this is just to show you how to do it.
Yay! I redid pretty much the whole thing! I redid a lot of the instructions because they were really confusing, and I redid most of the drawings. So, hopefully this is less confusing. Wahoo!
