I want to develop a game in a month by using the Cocos2D Open Source game engine. Learning Cocos2D is a bit hard and I don't know how to create my initial project by using the files provided by Cocos2D base project. I doubt whether it is possible? 

Can I learn by using Cocos2D base project directly and modify it for my game application? Does the license allow me to use like that? ( Because I can't learn all OpenGL programming concepts and develop an application in a month, which is very hard. )

Appreciate your thoughts and advice.

Thank you.
