The (now canceled) game was dubbed InkQuest and starred a girl named Sophie who finds herself trapped within a book called the Inkwell. Naturally, it becomes the player's goal to help her escape the magical world. According to the studio, "it was part magical map, part audio book, part adventure game," and "the concept was expanded further and built into a more robust, playable prototype."

Man, this game looks so charming. Is anyone else as distraught as I am that Lionhead decided to cancel it?
