Rating issues
Violence in the game is non-realistic in nature. Predators can sting, bite, throw or swipe at the player’s character, while the player’s character can fight back against predators, or attack prey to eat, by biting or swiping at them with its claws. There is no blood or injury detail and attacks simply cause creatures to fall backwards.
Other issues
There are some mildly scary sequences, such as a forest fire and the player’s character having to sneak around sleeping creatures without waking them.
