Here I would like to announced that my game "God Plays ball" is powered by cocos2d and chipmunk.
In this game you can draw to create a rock to hit the ball to scroll the ball ahead. it is just something to kill time.
The sale of this game is very bad. It adds up totally not more than 40.
I hope to contribute the whole project to our community after I add some comments on the code, if the code can help some fresh guy to chipmunk in chipmunk-sprite co-operation and so on.
Sorry for my late announce of this for so many urgent issues bothered me.
We are working on a "big game" with excellent art design powered by cocos2d, cocosDenshion and chipmunk(for the action of menu).
