Slendytubbies: Nihilism is a Slendytubbies fan-game inspired by I'm on Observation Duty. Monitor the cameras, detect & report different kinds of anomalies, and uncover what hides in the dark. Things go missing, creatures appear, and reality breaks when you’re not looking. Stay focused, report everything… and survive as long as you can. Beware however, a smile is watching you in the dark. Will you be finally able to answer those letters?
