This looks and sounds like a game I'd really enjoy to play, but I don't use Windows anymore.
Is this game playable on Linux through Wine, or better still are there plans for a Linux version of this game?

Hi there! Sorry, there are no plans for a Linux version. The reason is simple. I'm just a solo developer and wouldn't be able to provide support and test it properly on this platform. It might be possible that it works OK though. It works pretty well on S*Deck, so give it a try. Gog has a pretty good refund policy, so if it goes wrong, you can always return it.
