I bought the Steam version and run it in Wine on both an Intel and M1 Mac. I ended up refunding the Steam version and bought it on itch.io so I could just directly download the game files and updates instead of having to mess with Steam inside Wine (the Mac Steam does not allow you to download Windows files). Also you get a Steam key with itch.io, so when they release a proper Mac version I can add it to my library still.

There are (where?) some issues with missed mouse presses (double click issue) which make it really annoying to play, but there is a workaround for that which worked fine for me: https://steamcommunity.com/sharedfiles/filedetails/?id=28983...
