My game made with cocos2d-x has just been published on iOS: http://itunes.apple.com/us/app/precopter/id533585470?mt=8
It has a homemade trailer too: http://www.youtube.com/watch?v=1cfHka4ZLOw
It was a big journey. I started the project about a year ago with cocos2d-x.
Have a look and tell me what you think about it (http://www.facebook.com/Precopter)
Cocos2d-x is really a great framework! Thanks guys!
