There's no G in Psychonauts. And there's only one H. I am the bitchy pointer out of mistakes. Fear me.
Creepy is correct (or eerie, which would be my first choice). Terrifying it is not. There won't be any Silent Hill monsters jumping at you around corners or that type of thing. I don't... think.
You will find The Milkman Conspiracy eerie though. And Thorney Towers is mighty weird.
Don't neglect your bacon. I would never have figured some things out without that bacon.
