You will have to put yourself in the shoes of a child trapped in an abandoned school with which you must try to escape from an evil and terrifying nun who wants to use you to invoke the devil.
You have to solve small puzzles to complete levels, also having to be aware of the sound to know when the nun is near in order to escape to safety.
It has four levels of difficulty in which you must try to complete the levels making the least possible noise to not get the nun's attention and lose the game.
