In 'Whose Hello?', you play as a world-weary private investigator in a bizarre, retro-futuristic city. Your mundane task of tracking down a missing vocal signature leads you down a rabbit hole of eccentric characters, each with their own strange stories and hidden motives. As your investigation unfolds, you interact with the townsfolk, uncovering secrets while collecting audio snippets of their greetings. Everyone seems to have a clue, but as you get deeper into the case, you realize 'Hello' may not just be a greeting. Choices you make change the outcome of each character’s story and may even affect your own voice in this chaotic search for identity and truth. Solve puzzles, navigate quirky dialogues, and engage in a web of whimsical yet dramatic tales to ultimately confront the ultimate question: Whose hello truly matters?
