In 'Hello, Who Dis?', you play as an anonymous tipster who receives a series of bizarre messages on your phone from a mysterious sender known only as 'The Whisperer'. As you interact with the clues and the diverse cast of characters—ranging from a paranoid conspiracy theorist to a cryptic artist—you are drawn into a web of secrets that unfolds across your city. Every decision you make influences the outcome of the story and uncovers new layers of mystery. With a real-time response system, the game prompts you to reply to messages in a manner that shapes your relationships and ultimately decides the fate of the characters involved.
