To predate the game's release tomorrow, Steam Deck verification partially requires an announcement of how/if the game plays on Deck.
The game, both for its demo and the main game, through internal playtesting, run GREAT on Deck with no real issues, to my knowledge. Just boot up the game with no special settings and you should be good to go! Ideally you should see a green Steam Deck Verified status once Valve does their thing!
Oh, and your Steam Cloud will work just fine with it too, so don't worry about your progress not carrying over.
That's all for today! Thanks for the support!
