I liked a lot of things about this game, but my favorite thing about it was the pacing. The story revealed itself gradually without overly-long exposition or confusing gaps. The puzzles were just challenging enough to keep me engaged, but not so hard that I felt frustrated with them. And I could clearly picture each scene in my mind: the long empty hallways, the caves and tunnels under the station, and the protagonist herself, a frightened determined teen alone in an unfamiliar place.
