Game falls short of both the film and the book.
Parents need to know that Lyra, the main character, frequently deceives people -- often by lying -- to get what she wants. For example, she tricks a servant into letting her into her uncle's quarters, and tells her uncle that she's been behaving -- when she'd been throwing plum pits at a teacher. Iorek the armored bear kills lots of wolves and human hunters. There's no blood, but he growls and bares his teeth, and in one cut scene, he's shown biting a wolf through the middle and tossing it around.
