Hey, do you think you could export a native linux build? Godot has export templates for linux :3

I wanted to have a Linux version ready to launch at the same time as the Windows build, but unfortunately it had some problems, specifically the metadata for the maps wasn't being read. Hopefully I can get this fixed at some point, and I'll release it then. Until then, I've been told that running the Windows build with Proton or Wine works! Note that there may be some bugs with this, I haven't been able to try it myself.
