Just writing to let you know that the Linux native version of this game still doesn't render correctly. It's fully playable, but I can only see the dialogue and the mute button over a black screen. Making decisions in a dark room...
A year on and I doubt it will ever be fixed. I have just submitted an install script to lutris for the windows version, though it still needs to be approved by the moderators. If you do not want to wait, just install lutris, download the windows zip file, extract it, add a game to lutris and select the exe file as executable, lastly enable DXVK under runner options and you're good to go.
