The game seems to run alright, but I did have to force compatibility to Proton (Experimental or 7.0-6). It seemed to have launched with the Linux runtime, because it exited immediately out of the box, but forcing Proton ran the game.
I have seen mention on the Steam forum about issues on the Steam Deck, but I haven't experiemced them myself or maybe haven't played enough to find any of them.
I did have a problem logging into my account so that I could sync my save data. I get a black screen when I try to log in and I can only quit the game then with the B button. Desktop mode didn't not help, also showing a blank screen.
What I did was copy over both Saves/Options.rvdata and Saves/Options_0.rvdata to the Steam Deck game's Saves directory in compatdata and then my save data synced correctly.
Could not set up the game's custom cloud save system, solved by copying configuration files over.
Force compatibility to latest Proton.
Is Stable but Has No Music; Has Few Localization Errors
No background music ever played.
At some point before the start of Chapter 1 after I went through the flaming tower, I decided to look at the upgradeable Skills available to my characters; but when I looked, some Skill names were in Italian, even though I was playing in English.
I used an XBox One controller over a wired connection for input. When launching the game for the first time on a 4K display, the apparent window size will be very small. Press the B button when in-game after the first dialogue to access the Options > Video > Enable Fullscreen.
