In 'Whose Hell Is This?', players step into the shoes of Felix, an unconventional pet detective who specializes in reuniting lost pets with their owners. After a bizarre explosion at a local science lab causes random dimensions to collide, Felix finds himself trapped in a series of parallel worlds filled with eccentric characters, bizarre creatures, and warped versions of reality. Each choice leads to different outcomes, as players must navigate through absurd scenarios like helping a cat rule a canine kingdom or negotiating peace between rival worm factions. Will Felix uncover the secret behind the explosion, rescue the hapless pets, and find his way back home, or will he remain forever lost in these chaotic realms?
