Parents might want to think twice about Whiplash. It's morally ambiguous messages about animal cruelty might not be the best thing for impressionable young minds who don't yet understand the concept of satire – and the game is weak satire at the best of times – one of the main characters is a rabbit on a chain who gets dragged around and used as a weapon.
Sensitive people might protest the nonchalant way Redmond gets abused. He's a hardy little bunny and the game tries to be cartoonish about the violence, but nevertheless the main premise of the game is for a rabbit to get treated in ways that would quickly kill the animal in real life. Over and over again.
