I'm playing the game on Debian GNU/Linux 10 "Buster" with the Stable version of Wine provided by Wine's repositories.
The game is running perfectly so far, but when I quit it the screen remains very dark. I can see the desktop, but it's like the gamma has been turned off almost completely. I tried re-adjusting it both through graphical tools (Xfce Power Manager) and through a command found on WineHQ (xrandr --output {YOUR_VIDEO_OUTPUT} --brightness 1, substituting the variable with my screen) but none actually worked.
Has anyone else had the same issue? On other operating systems perhaps? How did you solve it?

How about xgamma -gamma 1.0? E.G. for NVidia you can also fix it via the driver control panel, but xgamma is faster.

or simply quit the game using the Alt+F4 instead, both options worked for me

Quitting the game with Alt+F4 worked for me too, unlike xgamma -gamma 1.0. Thank you both, the issue isn't fully solved but at least there's a workaround :)
