In 'Whose Mess Is This Anyway?', players assume the role of a disgruntled apartment complex manager who must navigate the absurd chaos left behind by their eccentric tenants. Each level presents a new catastrophic scenario, from unidentifiable stains to inexplicable smells, as they unexpectedly find out the tenants are hiding their secrets. Players interact with bizarre characters—like the conspiracy theorist who believes the building is a portal to another dimension—and must solve the mysteries behind each mess while trying to enforce the lease terms without ending up in the middle of a hilarious drama. The choices players make affect relationships with tenants and the overall flat's atmosphere, leading to multiple endings all tied together by the question: who really owns this mess?
