Hi! Your Linux build seems like it's perfectly set up to be an AppImage (a self-contained linux app that usually works across many linux distros!)
If you've got a spare machine, or if you'd like to set up a VM, it'd be perfect to bundle it as an appimage if you have the know-how! Why your compiler didn't do this for you already is a mystery...
Otherwise, the game runs nicely on my Arch machine!
