This will sound weird, but, if the game didn't have any controller plug-and-play support, it would actually become *more* controller-friendly.
The kind of controller support this game includes is not Xbox or PlayStation-specific. It's generic plug-and-play, meaning that it will force movement on "any kind of analog stick" or "any kind of D-pad". You can't take the keyboard defaults, plug them into a profiler (like JoyToKey) and create your own layout.
