In this interactive text-based game, players step into the shoes of 'Echo', a self-aware greeting that travels through a quirky universe made up entirely of social interactions and encounters. Players must navigate a series of bizarre greetings, witty returns, and hilarious misunderstandings across different locales, from a futuristic city where greetings can alter reality, to a medieval village where the wrong salutation could spark a duel. Each interaction shapes Echo's personality and impacts reactions from other characters, leading to multiple endings based on how well players handle the art of saying 'hello'.
