From Game Revolution: “Untitled Goose Game doesnt have traditional enemies you have to fight, but rather annoyed civilians who want nothing more than for the goose to leave them alone. One such civilian is the shopkeeper and her broom, with one of Untitled Goose Games objectives being to break the broom. Heres how to steal the broom and do just that.”
