Hi. As a long term Cocos2d-X developer, I recently have a huge attention on CocosSharp of Xamarin.Forms. Besides I get most of the concept without any problem, still lack of documentation especially for CocosSharp Xamarin.Forms (in my case) strongly felt.
For example: How to make a version 1.7.1 CocosSharp Xamarin.Forms Portable game full screen? Maybe the simplest thing, but a big shame for the documentation that developers can't manage to get it done.
