We finally ported Stick Stunt Biker to android using cocos2d-x. cocos2d-x is really mature already, we just discovered a few bugs here and there, but everything works rather nicely now. Integration of openfeint, market place, etc.. is easy too.
Market place: https://market.android.com/details?id=com.djinnworks.stickstuntbiker

If you have any questions or need help porting your game feel free to drop us your questions.
Thank you guys!
