* The place where it says the wrong way and then just exits the game was kind of funny.
* The place where if you go up or down the stairs one story, you get locked in an infinite staircase was sort of funny, but irritating. You can't even kill yourself so you HAVE to reload. Also if you're OCD like me you may spend 10 minutes in there wondering if there's some pattern to miss.
