While node webkit uses OpenGL and html5, if you made the same game in both CC and c2 you probably wouldn't be able to tell the difference. Don't let the web technologies fool you, c2 is quite superior in almost every way. It even renders faster than CC does!
well unfortunatey that is the dead end for me, exe only im afraid, if c2 was able to do this then that would have been great, do they not have an option where you can choose?
