In 'Whose Hello?', players step into the shoes of a first-class sound detective in a futuristic city where voices possess consciousness and can hold secrets. You are tasked with uncovering the identity of a mysterious figure known only by the phrase 'hello,' who has been sending cryptic audio messages that disrupt the delicate balance of a society reliant on vocal communication. As you navigate through layers of deception, gather clues from eccentric characters, and decipher echoes of the past, your decisions will shape the outcome of the story. Every whispered answer could either bring you closer to the truth or plunge you deeper into the chaos of voice hackers and rogue frequencies.
