Probably not, since it’s not mentioned.

Wish it was, because I wish this game got updated for Steam Deck. It’s hard to read files, since there’s no zoom, and no plain text option. And the game sometimes forgets you’re using a controller, forcing me to switch to mouse and keyboard to progress.

if true, not too bright to advertise a PlayStation upgrade on steam and not offer anything for pc users. Well i just won't buy the sequel since they wanted to cater so much to console users. i know my little boycott is pittance to them, but makes me feel better.
