Anyone else had issues with the Linux version?
Viewing post in Mirrored Escape jam comments
The game was actually built and developed on Linux, so that should be the most stable build.
If the issue is with launching the game, you can find the logs in ~/.local/share/godot/app_userdata/WMB Game/logs/
You could also try deleting the whole WMB Game folder if the logs don't show any indication of something being wrong, in case the shaders failed to compile or something.
Otherwise, could you please tell us more about what issues you're having?
