It was scary before the enemy showed up, because I didn't know when I could expect her to show up. But then when she does show up, I still found it scary for a little while, because I didn't know her patrol pattern. But now I do, and it makes the game not very scary anymore, like, at all. And I do rather dislike having to walk all over the place just to find some numbers, while having to keep waiting for the girl to go by in order to get to my next destination.
