I've uploaded a linux build if you want to give that a try, I don't have a linux machine to test it on so fingers crossed it works

The linux version isn't finding .NET; when .NET is involved from my experience it's less work to make things work with WINE rather than try to port the whole game. Either way, it's probably a lot of work for a very small amount of users, I thought it was fair to let you know the issue but I'm not suggesting you prioritize it over anything else you might be working on.
