I don't know much about the science of bears, but it seems like he would starve from not eating so long. Oh yeah, they eat both meat and plants. I appreciated how good the graphics were. Again, I do think this is a little too cute. There's really nothing that wrong with it, I guess. At least the bear looks happy.
I would think a bear would be able to take on a pig. Of course, this is a game with no fighting. It looks more like a boar than a pig. It is interesting to see what will show up in the next level. While not great, certainly worth your time.
