Controller support seems to be rather spotty. I've tried with both a Wii U Pro Controller and an Xbox One controller and have limited success. I was able to start a new game, but then am unable to do anything with the controller analog sticks, d-pad, buttons, shoulder/trigger buttons. Once I started the game with the controller, I couldn't even access the menu by using the keyboard ESC key and had to ALT+F4 the game.

Tried again today, and since I did the Prologue, now I can't move through the chapters with a controller and still have to default to keyboard. If I start the game with KB+M, at least I can I can access the menus by hitting ESC to properly quit.
