### Updates
Please note that this is an *iterative* book. As the open-source Cocos2D-X game engine grows it gets better and better, causing us to enhance this book. A [changelog](/game-source-code/cocos2d-x-platformer-engine/#changelog) will be maintained so you can always see what's new.
We hope you enjoy learning about making your own multi-platform sidescroller game!
