I've just updated the demo with a small patch addressing some small issues I found when players were playing:
[list]
[*] Added proper control icons/names where appropriate when playing with controllers.
[*] Enhanced the auto aim slightly, to auto update when getting too far away from a target.
[*] Made an option for dropping runes with Y when playing with controllers.
[*] Made an option to auto-equip runes with X when playing with controllers.
[*] Adjusted the difficulty a little bit down on the first difficulty.
[*] Added appropriate error messages when players try to do actions they can't
