I love C2! Such a breeze to make games in. It's just once finished, I can't get them where they're going to be played - EXE, Android, iPhone, XNA. I'm currently planning a new game as I'm tying up a game I've been working on for the last year or so... but I think I may have to try a different engine.
Big shame, as it's harder to develop for, but in the long run I think it'll be the best choice. Hopefully by then there will be native exports, rather than additional expenses.
