Thanks for the comment! Yes, I know how to do the HTML5 version :), I just got sort of demotivated about this as a lot of things didn't go quite as well as I was hoping. There's also some bugs I can't pin down in the physics and orbits drawing. I never made a third build, so you could say I've basically dropped out of the Jam, for what concerns me :D.
I don't want to drop the idea altogether, but I'll pick it up later probably. Just am not satisfied with where I could bring it in just 9 hours.
