Thank you for this, I managed to remove the gamepad in the rebind controls menu (I think I tried to click on it, and that specific menu was only accessible via the arrow keys, or vice versa. the menu systems are kind of inconsistent and each menu seems to prefer something different).
However despite not having a gamepad set, the game continued to use gamepad graphics for the tutorial, luckily I had tried it (and it ran perfectly fine) on windows first, so I knew the controls.
