Comes with 3 modes: Pencil, Pen, Eraser. 1 for pencil, 2 for pen and 3 for eraser. Press space to switch backgrounds. If you download it, run it in presentation mode, if you don't you will pick the pen up and it won't draw. Keep trying, and they will. The eraser, you have to click repeatedly to make it work. Very fun when you get used to it. Comment well, and i will make a version 2, with all new features!
