In this project, you must use the pen to make the entire canvas green. Once all of the non-green is gone (including on the background; it must all be pen green), you advance to the next level. Spray green over all the levels to win! I had this idea when thinking of all the green things in the library. There's a lot of green backgrounds, but the pen can make them even greener! Just move your mouse around. When only a little bit is left, helpful stars will blink to show you where to go.
