In 'Whose Diary Is It Anyway?', players step into the shoes of an eccentric amateur detective who stumbles upon a mysterious diary at a thrift store. The twist? Each entry seems to lead to a different bizarre incident among a quirky cast of characters in a small town. Players must read the diary entries, interact with hilariously odd townsfolk, and piece together clues while navigating a series of comedic misunderstandings. They'll collect items, choose dialogue options, and investigate the true owner of the diary, all while facing unexpected plot twists and absurd challenges.
