I know it's a long shot, but any chance of this coming out on Linux? Alternately, any success running this in wine?
All my games run flawlessly on Linux using various emulation methods. I send new builds to "Linux Game Consortium" to verify it works. So far I have never got a single report about any trouble (Proton, Wine, etc). Both stability and performance wise.
Details here: Linux support
While I'm unable to provide a native Linux port I always take a great care to allow my games to be run smoothly using emulation on Linux.
