I can confirm the game does run in Linux. I've tested it in Wine and a few versions of Proton-GE.
No winetricks dependencies or extra config needed at all!
When one starts a new game, the character sprites will be missing and there will be a white artifact on the screen, but if you manage to advance to the next room up the stairs those problems will fix themselves. Or just try skipping the intro.
The menus will still be messed up, though. But they'll be usable at least with the arrow keys.
Just keep in mind that the save and load screens look the same.

Here's the options menu for those who can't see it.
