Having a lot of trouble getting it to work. It only launches Quake, not the pak file. Also, where is the standalone version mentioned in the description?

The zip file in the downloads is the standalone package that you can play with vkQuake, Quakespasm, or Ironwail.
If you use vkQuake or Ironwail, after you drop the enyo folder into the Quake data folder, the enyo will appear as an option in the mod menu. In Quakespasm, launch the game with quakespasm -game enyo.
