It's got native controls. I'm just using whatever they had set up. It works pretty good. They all show up as button numbers though in the Steam controller profile, which is odd, but in-game I've had no issues just using the Decks controls as-is.
Sorry I should have been clearer. I was just asking if you're using mouse and keyboard or a console-type controller. And if it's the console controller, does the Steam version of the game give you the same UX that the game gives Xbox users with its radial UI?
