Who this book is for
This book is for game developers with some experience in programming games on one or more platforms already. If you want to leverage your game development experience on one platform to develop for multiple platforms and to get up and run quickly, this book is for you.
In addition, if you want to learn how using Haxe, OpenFL, and HaxeFlixel can make multiplatform development faster and easier, this book will show you.
Having prior experience with a language similar to Haxe, such as ActionScript or JavaScript, will help, but isn't required.
