Pretty interisting concept, but not much of a game yet. The system is a bit unbalanced and it tends to get quite buggy over the time. I think that different terrains should had different spawn rates for the animals, since it's random. It would be nice if some of the appex predators died if they did not eat enough or something like this too, that should balance things a bit more. I think it's very promissing, but it would probably work better with less RNG.
