In 'Whose Hello?', players step into the shoes of Sam, a quirky amateur detective with an exceptional but very peculiar talent: they can hear the echoes of greetings from the past. Stuck in a bustling city where identities are elusive and gossip is the currency, Sam receives a bizarre message from a long-lost sibling, leading them on a wild chase through the city's underground. Each character they meet has a 'hello' echo, revealing hidden secrets, forgotten grudges, and unexpected allies. Players must navigate through humorous dialogues, decipher cryptic clues, and make choices that will determine whether Sam digs up the truth or gets lost in the hilarious chaos of social interconnections.
