Reminds me of the film Au Hasard Balthazar by Robert Bresson in that any attempt to truly capture the essence and simplicity of an animal, no matter how clever, always flows against the human wants of media.
Fumito Ueda has already made two of the best games ever made. This however might not be one of them.
What it is, is one of the most experimental games ever made. One who's memorable vignettes speak louder than it's value as a piece of "media" ever could.
The word for it would be art.
