Heyyo, adventurers! Just a quick change in the Steam Cloud settings to make sure that Steam Deck users can get their Cloud Save! There is no downloads needed with this as far as I know.
[EDIT: 2025-03-12]
Using Steam Deck's Proton, the files of Deep Dark Wrath are in:.local/share/Steam/steamapps/compatdata/2891520/pfx/drive_c/users/steamuser/AppData/Roaming/CraftedCircuitry
The backup files from the Save Journal are saved here:.local/share/Steam/steamapps/compatdata/2891520/pfx/drive_c/users/steamuser/Downloads
I had no real clue of how Steam Deck/Linux works and had no previous plans on supporting them. I did kinda hope at least the Downloads folder used the actual Linux Downloads folder instead of a compatibility with Proton.
Once I release v3.0, I may look into proper Linux + SteamOS support!
