The early versions worked on Linux but apparently there have been some issues in newer ones.
I was pointing out the icons. If you use the wrong icon itch markets your game as a Linux game. Due to the icon not being the Apple, it does not market it for Mac.
I do not know if there was a Linux version before. I am using a program called 'usebottles' with no problems. <right now> I just tried it with normal 'wine' which did not work. It might work with Proton. (^_^) I am lazy to set it up right now.
(^_^)/ Thank you for the reply.
