ILabyrinth

Scary App is an iOS application made by Cyoshi Games. After the splash screen, the app pretends to be a fake game called iLabyrinth and tells the player to beat all three levels. However, at the end of the third level, a picture of a zombie woman appears along with a scream. The app then takes a photo of the player's reaction.
