Hey I'm running into some technical issues. I think when you export in Godot, you need to package up the files surrounding your `.exe` (windows) and `x86_64` (linux). For mine, there is an associated `.pck` file and others files.
I can't get passed the start screen on linux, and when I virtualize the windows version with wine I can't click on a card during a fight.
Windows Errors:
