I really like the concept of it and think that it was executed mostly well. It's annoying how the story campaign works, where you need to play the survival portion a lot to unlock little side stories. I would have rather just had a normal campaign. However, I understand that's my own preference because I don't love having to restart once I die, which survival is. But playing as different animals in the ecosystem is entertaining because you have to deal with the different levels of prey/predator.
