One of the most tedious games I have ever played. The True horror is wanting to find an item, solve a puzzle or just backtrack while the Janitor is always finding you, no matter how stealthy you are (which also means, that crouching is a huge waste of time because it doesn't help). And, if you manage to hide, you have to spend some 10-20 minutes afk just to wait for him to stop camping the door near your hiding spot.
