Fwiw, if you download the Itch client and buy the Windows version of this game, you can run it via Wine. The Itch client supports Wine and will run Windows games automatically via Wine if you have a Windows game installed.
This game works great with Wine, albeit with two issues: 1. The mouse can move outside of the game window onto other monitors, and 2. If you Alt Tab and then get back into the game, you can no longer control your character and have to restart the game. It autosaves very well so for the 2-3 times I had to restart no progress was lost.
I would just buy it on Steam if I hadn't gotten a free copy of the game for Itch.
