In a quirky town where greetings are taken far too seriously, players step into the shoes of Detective Echo, a master of social cues and etiquette. When a prominent local figure mysteriously collapses after being greeted with an unapproved 'hello', it’s up to Echo to navigate a tangled web of eccentric townsfolk, each with their own unique way of saying hi. Players must engage in dialogues, solve hilariously bizarre puzzles, and piece together the backstory behind each character's preferred greeting, all while racing against time to prevent the next miscommunication disaster. Will you uncover the truth behind the 'Hello Heist' before it's too late?
