An interesting concept.
Good stuff: Learning to take care of an animal in the long run is a nice strife. The plans seem well thought through. Room for improvement: Sounds would be nice. I felt a little detached from my animal (pig) when it is only a few pixels. It would be great to show it as the main theme somehow (and wether it is doing good or bad). The menu could be more intuitive (had to watch the video to know what to do).
