Evil Nun: Schools Out traps you inside a decaying school filled with classrooms, basements, and hidden areas. Your objective is to collect key items and solve environmental puzzles to unlock your escape route. Meanwhile, the nun patrols the building and
reacts to the sounds you make. The gameplay emphasizes stealth and risk management. Opening doors, running, or interacting with objects can alert the enemy. Players must memorize room layouts, plan efficient paths,
and use hiding spots wisely. The tension builds from unpredictable encounters and limited safe zones.
