Also, for the Devs. PLEASE, Pretty please! Make a spot where we can at least SEE the button mapping! Adjusting isn't neccesary, just seeing them rather than finding it out ourselves saves quite the headache and negativity in the reviews!
(Edit. There is a "Guide". However it can only be found while in the pause menu during the story. NOT at the Title screen!)
