At the time of writing, the action game is in closed beta, and it doesn’t offer native controller support. However, it does have an option that players can use to play the game with a controller.
With that in mind, the game is likely to feature controller support when it releases on PC, as it is expected to be Steam Deck compatible.
However, you must keep in mind that since the game is still in early development, it doesn’t offer any key binding or customization feature.
Additionally, even with a controller on default settings, some key actions in the game may not be mapped, so you might encounter limitations during gameplay.
In the near term, if a keyboard can do what you want, if you can dig up macro software for your platform that can look for specific gamepad combinations and send keystrokes as a result, I imagine that you could make it work that way.
