Nice idea. Wile I'm sure this has pretty heavy constraints it could be a great way of prototyping ideas, and of getting into games design.

Players simply design their level by hand, creating any traps or obstacles they want the avatar to surmount while climbing five stories and reaching the goal. Pixel Press uses proprietary character recognition to allow the iPad's camera to pick up the sketches and convert them to graphic elements in the level. Then the creator has to test the level, refine it and add skins to make it look like a polished game

Robin's Kickstarter is already a quarter of the way toward its goal, so here's hoping it'll be funded.
