The spirits eventually abandoned the world, leaving the AI to take control and corrupt the inhabitant's leader, Steve, transforming the entire realm into "Error 437".

Psychological Horrors: The game is said to break the "fourth wall" by displaying error messages outside the game window or playing loud, unsettling sounds like "Disc 11" or "Death".

Entities: In updated versions (Download UPD), Herobrine is a frequent stalker who may appear behind the player or cause the game to crash after a battle. The "Virus" Warning
