the game has a wonderful idea, and i quite enjoy it however i find that the ghosts and spawns of them can be a little unforgiving. (can't think of a better word but there is one) they very often are stuck in a long hallway next to either your objective or entrance. and personally i have yet to even complete a game .... even on easy .....
then again i may just be garbage at the game. either way it is a wonderful concept and lovely music to go with
The idea is that if you have enough sanity, librarians rarely can prevent you from achieving your local goals (reading a book, checking the catalogue, taking the right exit). If a librarian doesn't see you (while you are in the L-space or behind a corner), you can safely pop into his line of sight as long as you know that you'll be able to hide from him on the next turn.
