@thewebinator Sure it can, just let the screens suddenly switch places or reverse controls. There are enough ways to mess up the human brains. Though I doubt it will be any fun then, cause any harder and I'll start cursing :p
What is it with killing the guards. "Hey, I killed all the guards and there is only a green helpless guy left, wow, I must be good.". Where is the challenge if you were able to and about the footprints, those are just to make the game look good. If it wasn't there, you had nothing to whine about. But dragging the boss, that would be awesome.
