About This Demo

Some things are better left alone, but curiosity killed the cat- didn't it?

A year after the car crash that took her mother's life, Kit finds herself facing yet another shocking loss- the murder of her beloved cat, Arthur. In shock and with little else left to lose, Kit follows a trail of clues that lead her into a bizarre other world. Out of place (and potentially out of her mind), Kit is left to fight her way back home, all while enduring the changes this new world has to offer, and searching for Arthur's murderer.

Who Killed Arthur? is an offbeat murder-mystery, puzzle game that details a story of heartbreak, loss, body horror, and the fear of growing up. It is rife with rich storytelling elements, strange, talking animals, curious children, and a killer original soundtrack to boot!
