Sorry! I found out it works with Steam on Linux and with Wine on MacOS. Great game!

Yes, Wine has been available for everyday use on Macs since 2007. Before that, it was more for nerds with too much time on their hands. :-)
It was a bit fiddly (thanks to AI, which solved the problem in seconds :-) ) but now it works perfectly, even on Apple Silicon.
I know I'm repeating myself, but it's a great game!
