The movements made me dizzy quite fast ^^'
However, the concept of moving with this restricted field of view is very nice, and the animation goes with it too!
Maybe it could be nice to have some kind of compass, to know you can go beyond the dark to find food/enemies ect..
Because otherwise we move without a destination in the hope of finding what we are looking for, but that is also part of the dramaticness of the game, so i would see why it's like this ^^
Very clean and polished experience, well done!
