There were a couple things you missed, in case you want to go back. 1. Before talking to Mary Ann the second time, after you looked at the books, you could have gone to the right and looked at the various screens in the wall. 2. You can go all the way to the right on the second floor to interact with the organ. 3. Check your notes while driving around on the Zero - the brochure you picked up added a couple of spots you can go and look at. The way driving on the Zero works is that there's a main loop - the 65 - with various smaller loops branching off. You switch tracks by reversing, the buttons are there only to let you know there's a branching point there. The catch is that you get a different set of landmarks depending on driving to the left or to the right.
