In 'Whose Diary Is It Anyway?', players dive into a surreal world where they are thrust into the role of a quirky literary detective. After a peculiar subway mishap, you find yourself in the chaotic Library of Lost Thoughts, an expansive library that houses the secrets, dreams, and embarrassing entries of countless individuals. With only a talking pen named Scribble for company, players must explore the handwritten diary entries scattered across the library, piecing together clues about their owners. Each entry presents a different whimsical narrative that unfolds into dramatic dilemmas and comedic scenarios. Can you unravel the tangled stories and figure out whose diary belongs to whom before the library's boss, an eccentric old librarian, catches you?
