That would be me!
Looks like there is a Jack McLantern Linux port available, but untested... I'm going to check it out
I was able to download it and launch it, but upon loading everything is black except the HUD. I tried different resolutions and quality settings, even disabled everything in-game settings but nothing... just black. I can hear Jack running around and interacting that is about it.
