 # A nix flake for building cubyz, (https://github.com/PixelGuys/Cubyz), 
 #   an open source 3D voxel sandbox game.
 # SERIOUS LIMITATION: cubyz uses their own custom patched zig compiler ୧(๑•̀ᗝ•́)૭
 #   to build, you will need to do nix build --option sandbox false.
 #   This is because the custom zig compiler looks for dynamically linked libraries
 #   in an FHS environment. There are ways around this but I'm too lazy to solve for now.
 # IMPORTANT NOTE: use `zon2nix` to generate a local deps.nix file with dependencies.
 #   It may contain local files that don't exist on your computer, so just delete that
 #   that dependency from the zon file.
