For who can't run AlternateWatch.exe at wine/proton in Linux, just open AlternateWatch/Binaries/Win64/AlternateWatch-Win64-Shipping.exe instead. It's working very fine on my local after I found this way.
I tried that and nothing happened. also, what do you mean wine/proton? I'm an ubuntu user and I just wanted to get this game to work.
Don't you know wine? How do you run windows softwares in Linux usually?
I'm using bottles to run a wine.
