I am new to cocos2D and just download cocos2D-X today.
First view, I am little surprised that the hello world source code in win32 project is much difference from other.
Then I tried to copy most code from iPhone project to win32, replace the same part, the code runs well.
I suggest to change the hello world on win32 to same as others to avoid the confusion.
And I would like to put all source code of hello world to a seperated folder on the same level as all projects, on each projects, reference to this folder for .h and.cpp. It will make all change on the source code to be available for all projects at same time. This is the value of cocos2D-x, I think.
