'World's Greatest Cake Theft' is a 3D detective game for PC. The player takes on the role of Cane McMuffin, as he tries to find the person responsible for stealing the holy cake of deliciousness.

The player must explore the city, talking to its residents to gather clues. While speaking to any character, McMuffin may express doubt, or use collected evidence to draw out more information from his questioning.

The game has 12 major events that must be solved before getting to the thief, divided across a week of in-universe time. While at the start of the game the player only has to pressure regular citizens, finding ways to press and obtain evidence gets harder as McMuffin comes to the realization that the real culprit comes from within the police force, effectively being above the law.

The player loses if they present too much faulty evidence in a row (sometimes resulting in McMuffin being fired!), but this only takes the player to the start of the event, so there isn't much time wasted.
