Hello @P4NCH1, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/894#issuecomment-419732333.
I saw it @kisak-valve but that's a whitelist request and nobody spoke about this problem. And is not only a problem in this game (on SteamOS) but in others too, issue that is not in other systems like MX Linux 17.1
I'd opened a one-game issue because of the requeirements to open one, but it's more a SteamOS+Proton problem than a game problem.

Symptoms
Keyboard doesn't work ingame or even in menu selection. Sometimes works in menu selection but when game starts and you have to move the character you can't. If you [Alt]+[Tab] out, the game freezes so this is not a workarround like in MX Linux
Reproduction
or
NOTE:
The game have the same issue in another machine with MX Linux 17.1 64bits but keyboard gets detected again ingame by removing the focus off the game and returning it ([Alt] + [Tab]).
