The text can be overlooked. The game definitely doesn't pop-up with suggested buttons, etc even when using the Steam Deck's controls, so you might want to spend a minute mapping everything to places that make more sense. For instance, both fire buttons are, by default, the shoulder buttons instead of the triggers, something like this should probably be flipped for comfort when playing.

Cannot confirm if there are sync issues. Steam on PC would indicate there are not, but the game isn't wanting to load properly on PC, ironically enough. Funny when something seemingly works better in proton thatn windows 11..
