I really like this book and the work Raydelto did writing it. This book teaches you from scratch how to develop games using Cocos2d-x and how the JNI works. I know this book will be useful for anyone who is new in this framework or has experience in it. I read each chapter and I can say that Raydelto wrote each chapter well, so I'm sure this book contains his passion and each reader will enjoy and learn because it is an excellent book.
