Does the Windows version work on Linux? There's a native Linux port, but it's horrendously outdated, so I think most modern Linux machines aren't able to play it.
Most Linux Machines will simply use Wine64 or something, which allows Windows games to be played on Linux, albeit to a degree. It depends how the game is made. If it's made in RPGMaker, there will be missing fonts/text and whatnot, but it should still function. If it's made in Ren'py, there shouldn't be any issues. Unity is able make both the Windows and Linux executables.
But if there is a Working Linux Port, I would suggest adding it via .zip.
