From the name of the game you can tell that drawing is the gimmick. But what sets this game apart from other games is you have to platform as well as draw. Although this game didn't intend that, it is still a feature almost every speedrunner of this game uses. But how do you draw and move at the same time? well have your left hand on the arrow keys and your right on the mouse. (If you are a righty about to complain about a lefty 75% of the lefty's use there Right Hand for the mouse) Another thing that makes this run easier is jumping then drawing.
