In 'Whose Hello Is It, Anyway?', players step into the shoes of an aspiring detective named Jamie, who attends a bizarre literary festival where every author is mysteriously disappearing, only to reappear with absurd characteristics and even wackier stories. Players must navigate through a web of comedic misunderstandings as they piece together clues while engaging in ridiculous banter with eccentric authors, over-the-top fans, and an unflappably odd festival organizer. The goal is to uncover whose greeting leads to the next monumental disappearance while keeping the hilarity alive amidst dramatic plot twists and humorous revelations.
