That should give you HaxeFlixel and all of it's setup and shit. If you run into issues, ask them in the #flixel channel in the Haxe Discord server: https://discord.gg/5ybrNNWx9S
Other installations you'd need is the additional libraries, a fully updated list will be in `Project.xml` in the project root, but here are the one's I'm using as of writing.
Once you have all those installed, it's pretty easy to compile the game. You just need to run 'lime test html5 -debug' in the root of the project to build and run the HTML5 version. (command prompt navigation guide can be found here: [https://ninjamuffin99.newgrounds.com/news/post/1090480](https://ninjamuffin99.newgrounds.com/news/post/1090480))
To run it from your desktop (Windows, Mac, Linux) it can be a bit more involved. For Linux, you only need to open a terminal in the project directory and run 'lime test linux -debug' and then run the executible file in export/release/linux/bin. For Windows, you need to install Visual Studio Community 2019. While installing VSC, don't click on any of the options to install workloads. Instead, go to the individual components tab and choose the following:
This will install about 22GB of crap, but once that is done you can open up a command line in the project's directory and run `lime test windows -debug`. Once that command finishes (it takes forever even on a higher end PC), you can run FNF from the .exe file under export\release\windows\bin
As for Mac, 'lime test mac -debug' should work, if not the internet surely has a guide on how to compile Haxe stuff for Mac.
