Proton GE (Glorious Eggroll)
Just go on GitHub, follow instructions on how to install Proton-GE and add it to Steam, and use it.
Needs mf-install (https://github.com/z0z0z/mf-install) to play the videos
Alt-tabbing loses the keyboard focus that can only be restored by restart
Lags in some cutscenes and sometimes when changing the scene, but not unplayable
The game can be played up to the second act by skipping unplayable videos mashing esc, mouse left and right buttons at the black screen. But to go after that you need to restore the videos functionality by running the mf-install (the second act video is unskippable)

Black screen when starting a new game
After the initial launch, the black screen also appears but I was able to skip it by pressing the ESC button. Maybe it was some CGI / cutscene. After that, the initial menu was launched. Pressing new game leads to one more black screen that I was unable to skip
