Hey! So i could enable an experimental linux version but problem is there's visual disparity between the windows build that uses directx and linux that uses opengl. Some things are missing, lots of "shader pink/black", and users reported bugs so I temporarily removed it from itch. To workaround this the projects being ported to the latest game engine but dont have an eta on that release yet unfortunately.
Ah, sounds like a bunch of broken shaders then, once you've got it updated give me a shout over on https://www.gamingonlinux.com/ and I'll happily cover it!
