Awesome stuff. Just spent 20 minutes with my 4 year old tweaking settings in the platformer example to see what the results would be. He loved it. Way more fun (for him) than the other day when he asked what the modulo operator was.
It bums me out that the economics of indie games are so awful. The kid in me wants, so badly, to make a gigantic, sprawling version of Zelda or a dungeon crawler. But there's no way I can justify the time investment.
Still, seeing an API this simple is inspiring. Props to kitao.
