In a world where people can literally hear their own hellos echo back, you play as Alex, a curious soul who starts receiving cryptic messages from the future via the echoes of 'hello' spoken around them. As you explore a sprawling, interconnected city, each hello reveals hidden truths and dark secrets about your past and the choices you must make. You will engage with quirky characters, unravel conspiracies, and confront the consequences of your actions. But be careful—every hello might alter reality, leading you deeper into a web where trust is scarce, and betrayal lurks around every corner.
