In 'Hello, Who's There?', you step into the shoes of Jade, a cynical freelance investigator with a knack for uncovering the bizarre. You receive an anonymous message inviting you to a secretive and high-stakes party in an abandoned amusement park. As you mingle with an eclectic cast of characters, each harboring their secrets, you quickly realize that the party is a front for an underground society, and someone is missing. Engage in a series of dramatic dialogues and make decisions that will lead you deeper into a web of intrigue, deception, and dark humor. Unravel clues, solve puzzles, and confront your own past as you race against time to uncover the truth before the night ends—and before the partygoers discover your intentions.
