Your adventure begins when Alex discovers a disturbance in the fabric of time, causing people across different eras to lose their ability to greet each other, leading to chaos and misunderstandings. As you journey through medieval banquets, futuristic dystopias, and strange alternate realities, you'll collect phrases, solve riddles, and engage in witty dialogues to restore the lost art of conversation. Each choice affects the outcome, and your interactions can either mend time or plunge it deeper into an apocalyptic silence. Prepare to juggle humor, drama, and quick thinking as you navigate the intricacies of multi-timeline interactions.
