"XBOX Controller is supported and recommended" is a bit of an understatement. Until I plugged in my controller on a whim to see if it would work, I couldn't interact properly with the menu - there seems to be no keyboard key (at least not on my keyboard) that could activate any menu item - including the control help where it recommended using a controller.
Also, something seems weird about the viewport. I don't know if it's intended or a bug, but if feels weird that when walking right the viewport is such that I'm near the right edge of the screen, so I can't see where I'm going (and walk off the screen for a bit before the scene changes).
