@gamingonlinux I was playing it for a few hours tonight!
It's really well done and runs perfectly on Linux (Fedora Silverblue, Steam Flatpak, AMD GPU).
The one issue I did hit was accidentally enabling cross-save, where it tried to sync (and the server must be super busy at the moment) and it hung, preventing saving from happening.
Cross-save is probably only needed for console to PC & back — I'm assuming Steam PC to Steam Deck works via Steam.
Anyway, people should have cross-save off. 😉
