Not really sure if this should be counted as feature but...

What feature do you want to get added on the base engine?

You should add a link to Haxe's Linux install instructions in the do NOT readme.txt or a new BUILDING.md file, due to how you need to add a different apt repo to install the latest haxe and haxelib commands. And it might help to mention to use the source folder when using haxelib setup. The entire setup script would look something like this (assuming you already cloned it):

sudo add-apt-repository ppa:haxe/releases -y
sudo apt-get update
sudo apt-get install haxe -y
haxelib setup ./source/
haxelib install #Look at the wiki for once!
haxelib run lime setup
lime test Platform #hope it all works out if not, welcome to being an actual programmer!
lime build Platform

The lime test part of it is optional but really useful for finding errors which are plenty but it saves you in the long run. Anyways for the people who are looking at this and wondering, "but where do I find the libraries I need?". Stop asking the devs for ****s sake and look at the oh so expertly crafted WIKI! I MEAN COME ON! Does no one who isn't a developer or software engineer understand how hard it is actually programming or delivering a product only few will enjoy but most will complain about. ESPECIALLY WHEN YOU AREN'T GETTING PAID FOR IT!

To test your sight, and reliability, please select the option of what should NOT be requested.

I just found out there is already a BUILDING. md 😅... Although some minor changes could still be made so this will stay open by me for now.
