Run from crazy psycho in dark frightening school. You ended up alone with this scary girl who is obsessed with you and you have to escape.
The game presents you the new antagonist – she is smart, her attitude changes and you can’t predict where she will appear. To escape you need a special key, but it is laying in the last closed room, so complete various quests to reach it. Everything becomes harder because she is chasing you and can appear right in front of you. And dark halls make passing impossible – you don’t have a flashlight.
