@HENOOB naah, don't be a purist about it. Don't make every kid learn Java before they can do something enjoyable, especially if it's a hobby. Learning haxeflixel IS learning Haxe in a way, since it's the language it runs on. Saying that you need to learn OpenFL as a fundamental for Haxeflixel misses the point; It's a framework that makes it easier to get started. If you're making something conventional then you don't need to touch OpenFL, it's just what powers HF.

That is very well put, but i think people new to haxe should learn how to use the programming language and its features first and then openfl and the flixel https://keyreal-code.github.io/haxecoder-tutorials/

This is about haxeflixel installation, and you can learn those things in tandem.
