In a world where greetings have been weaponized, you play as an unassuming librarian who accidentally awakens a long-dormant curse that causes every 'hello' to summon absurdly eccentric characters from different dimensions. Each encounter is a mix of humor, chaos, and clues, leading you to unravel the mystery of who, or what, is behind this bizarre greeting epidemic. Navigate through chaotic conversations, solve witty riddles, and use your own clever hellos to send these characters back while piecing together the puzzle of the hovering threat that aims to engulf the world in perpetual greetings!
