I really love the content of this game, and I was happy to buy it.
In a way that's not unique to this game, the Unity Input system is a disaster. Words like "Horizontal" and "Vertical" appear in WAY too many places, so you can't get a bearing of where you should be placing analog stick and button commands. It would've been easier for the game to not have any built-in controller recognition code at all, and just leave that job to profilers, like JoyToKey.
