Looks like the linux export is requiring glib 2.38, which is really quite new so isn't available on all distros (at least not in their stable ones), I don't know if you can get godot to drop it down to 2.36 (which is debian stable's version, so is safe to assume everyone has), but figured I'd leave a note here for anyone else that gives this a try! I'll just play on web for now, though, let you know how it plays later!
