Whose Hello?

In a quirky metropolis where every citizen communicates through cryptic greetings and clever wordplay, you play as a young linguist named Sam who receives a mysterious package containing an ancient 'Hello' lexicon. When your eccentric neighbor is found unconscious, you must navigate through a labyrinth of linguistic puzzles, secretive social circles, and outrageous characters—all while trying to decipher who said 'hello' last. Each character you meet drops clues in their unique speech style, and your choices will direct your path through the bustling city, revealing truths and generating unexpected allies and foes. Can you piece together the mystery before time runs out, or will the last 'hello' be yours?
