Book I - Starting Out, GNUSTO
Act 1 is a scene. Act 1 begins when the entire game begins. Act 1 ends when the player's capture ends.
The time of day is 11:15 PM.
When Act 1 begins: mark checkpoint act one as passed.
At 6:00 AM:
if the player's capture is not happening and the player is regionally in the Library:
say "Hm...it's 6:00, and you've seen no sign of the library opening. Maybe your timepiece is fast[if the player's capture has happened], or maybe everyone is too preoccupied figuring out what happened in Borphee[end if]?".
Door-puzzle is a puzzling scene with puzzle description "getting into the library proper". Door-puzzle begins when Act 1 begins. Door-puzzle ends when the Antechamber is visited. When the door-puzzle ends, close off the entrance. [The player can't go back after this.]
