When I launch the game with an xbox 360 controller, I don't get any warnings about the lack of controller support, and it says "Full controller support" on the store page. But:

• the Controls section in the game only lists keyboard controls
  
• the first thing I am told when starting a new game is to use WASD or arrow keys to move, and to press "E" to continue
  
• attempting to change the resolution from the settings menu with a controller does not scroll the resolution list when the selection goes too low, so I have no idea what resolution is being selected

I can use the controller to move with the sticks / jump with A / attack with X / etc, but I had to discover those by trial and error rather than checking the settings or learning in-game. Is the game supposed to support a controller in-game?
