STEM Game Challenge
I know people are trying to get C2 into education and everything, and I found out about this game challenge for Grades 5-8 and Grades 9-12. They don't list C2 on the site, but they do allow other engines to be used than the ones listed.
I think it would be some good advertisement on how C2 can be used by kids in an educational environment, and they do have an option to contact them if you are a maker of another game creation tool (which C2 is).
