Anna puts the player straight into the game without much of an introduction. You start off in a field next to what looks like an abandoned house. You must solve puzzles, eventually progressing through the game and into the house, where more puzzles await. The house is inherently creepy, and looks like something you would see in a horror movie.
While playing, you will encounter creepy events that happen at random. Things may be thrown at you, something may break, you may even see something moving in the shadows. All of this together makes for an immersive atmosphere that is sure to scare nearly anyone that plays. This game is not a action game, it is purely puzzle oriented. You will not be chased around by a monster or forced to defend yourself. The game scares you with the amazing atmosphere that it presents.
