Alright, there's a Linux build up now if you want to give it a try. As mentioned, no guarantees if it'll work or not though.
I appreciate the quick build! It does crash upon startup, though:
If you want someone to build & test Linux builds, I could do it, as I am building my own games with the Godot Engine as well, with a focus on Linux & HTML5 builds.
In exchange, perhaps you could build Mac & Windows versions of my games.
