A friend showed me this game that a friend of his made. Despite the cute style, the puzzles get devilishly difficult fairly quickly, which is why I thought readers of HN would be interested! Despite many hours, I have no idea how to complete some of the later levels. The gist is that each color behaves differently in a unique, weird way that makes drawing the requisite picture difficult. I highly recommend starting in the sandbox to get a feel for what each color does. The sandbox is last in the list of levels.
