I made a post a month ago maybe for info on possible Linux build. I think someone said he was going to try with Wine...? Does it work? What is the current situation with running Soulash on Linux?

I haven't heard for a while, but a couple of minor versions before, the game worked on Wine without issues. You could try to run the demo.
I have the linux build on the back of my head, but at this time I still have to push it for later, probably after v0.3, because it requires significant time commitment and will likely introduce extra layer of issues. :)
