Very cool! The seamless way in which the animation on the character is blending from normal walking to "wounded-cold" is done very well and adds a lot to the general atmosphere of the game. Just the way everything went from relaxing to unsettling, how you slowly realize that the only thing you can see are dead trees and your own trail. And then at the end how you're just watching snow fall on the poor guy while everything turns completely dark.... really awesome work there!
