Set in a quirky, alternate version of a bustling city, players assume the role of Della, a street-smart investigator with a knack for solving whimsical yet dark mysteries. One night, Della discovers a mysterious shadow that seems to have a mind of its own. As she follows the shadow through the city, she encounters bizarre characters, engages in witty banter, and uncovers a series of bizarre crime-related events tied to the shadow's origin. The game is filled with choices that affect the plot, allowing players to explore various paths in solving the mystery — all while dodging absurd obstacles and delightful, eerie encounters. Players must decipher riddles, collect clues, and occasionally outsmart the unpredictable shadow itself, leading to multiple endings based on their decisions.
