The game runs fine on Linux in Wine. I have tried both 1.0.0.27 and 1.0.0.28 with and without the DLC on Ubuntu 20.04. I have not finished the game yet and will update if I run into any issues.
Runs on Linux in Wine, on my system the Lutris default did not work and I set it to use the system Wine.
A settings menu would be nice. I was not able to get it full-screen on the monitor I wanted, so I played in windowed mode. Alt+Enter toggles full-screen.
