I was looking to download this game, but when I went to download, I saw that MacOS X and Windows were both on Version 13 while GNU/Linux had only Version 2. Please build the latest for GNU/Linux so everyone has the same version.
The version number you see here on itch.io is not the actual version number of the simulator. itch.io just shows you how many files I‘ve uploaded for a certain platform. I only recently began to include Linux builds at all. All of those builds have the same version.
That being said, I won‘t be fixing any Linux-specific bugs and the Linux build might be missing some features here and there. That‘s the only condition under which I‘m able to offer a Linux version at all. It‘s either this or no Linux version.
