This is a great game, but very hard. Is it intentional that you can bump into shadows when you haven't seen them? The thing is: you have to see them, to know where to avoid. But seeing them means stress and them following you, and not seeing them means bumping into them and stress also. So it seems to me, that you only can loose, because with every strategy you are doomed to be stressed.
Still, i love the concept and the art and i LOVE the weeping angels! :D
