In the initial "SURVEY_PROGRAM" release of Chapter 1, the Librarby's computer lab entrance uses a single door; Chapter 2 however changes this to a set of double doors, with the accompanying sign being horizontally squished and moved to the left side of the doorframe. Several stray pixels in the Librarby interior are also cleaned off.

Because Chapter 2 takes place just one day after Chapter 1, the Chapter 1 & 2 release changes the Librarby interior in Chapter 1 to match that of Chapter 2.
