That's a good question! I am actually not sure lol. I selected Linux, PC, and Mac but never tested out the Linux version since most players have PC and Android so I prioritized those platforms first. I never knew what Linux peeps use to run the games, whether it is still the PC version or they use the linux.tar.bz2 file. I probably would need to ask around to see what they use!
In my Renpy build section, there is Windows and Linux. I believe Tom have those there in case you only want a Windows build or only want a Linux build. When you open a PC zip, it has both an exe and sh (Windows and Linux executables).
I believe it would work fine on Linux because Tom builds, tests, and builds on a Linux machine. macOS, it is a hit and miss. So likely, you would only need PC to handle both Linux and Windows machines. :)
