In a world where everyone mysteriously disappears after saying 'hello, who's there anyway?', you play as a quirky detective with a penchant for the absurd. Armed with your trusty notebook and a collection of bizarre allies—like a paranoid ghost who can't follow simple instructions—you must explore a parallel dimension where greetings hold the key to untold secrets. As you unravel the strange phenomenon, you'll encounter perplexing puzzles, eccentric characters, and the unsettling question: is anyone really there to greet you? Your choices will shape the outcome and determine if you can unveil the truth or become another echo in the void.
