FYI, the Linux build crashes on my machine in the loading screen. I have 16Gb RAM, 1050TI, some i7. Most games work fine for me with wine or native. Here's my output log: https://pastebin.com/Xhx1i32j It looks like it's something with mono, which is how linux executes .dll and other .NET/C# stuff. Hopefully that is helpful.
When I run the the Windows build with wine it seems to work OK, reviewing now. This looks amazing as I'm sure you already know.
