In 'Whose Diary Is It Anyway?', you play as an amateur detective stumbling upon a locked box filled with diaries in a cluttered thrift store. Each diary belongs to a different, eccentric character from various backgrounds—an aspiring artist, a reclusive author, a secret agent, and more. As you delve into their lives through their writings, you must piece together the clues hidden within their stories to solve the overarching mystery of an unsolved crime. The unique twist? The diary entries dramatically shift based on your choices, with endings that can branch out in unexpected, and sometimes humorous, ways. Uncover relationships, confront rival detectives, and use your wits to determine whose secrets lead to the truth!
