The game is weird, with the default proton it works kinda alright, just don't dare to minimize or click on the game screen, you will lose any kind of input on the game and you should close it manually (wine services stays open on the background, so you should kill those process too)

Using GE-Proton makes the game a mess, sprites gets bigger one over other and it's impossible to see.

Overall it's a mixed experience, but it's not really playable if you can't click on some options.
