You mean you want the keybindings to match the Steam Deck buttons? Or is there something else specifically you want for the Deck?

I think it works fine, I use the touch pad for aiming I think it feels better for stuff like this

Set it to behaves as mouse

I'll look into doing that for default controls. Do the new defaults work, where N+M keys are binded to D-pad?

I can't get the fully supported on Deck tag unless I add button icons instead of keyboard keys to the tutorial and options menu, I think. But there's still the problem of taking 60 seconds to launch the game unless you're using Desktop mode.
