As it is well known, the pager in the second level misleads the player with a bunch of passwords in an extremely verbose fashion, which is intended to reflect the differences in character between the pager and the devil. However, some people may treat those randomly-cited passwords as the real ones. Hence, I've decided to:
No modifications at all!
Well, to be serious, I've in fact slightly modified the logic of this section. Due to the fact that the passwords obtained by the players are persistent, getting the passwords beforehand may lead to a mismatch between the monster's dialogue and the player's status. Therefore, I've altered the logic of this part to accept password inputs only after you've acquired the pager.
You should have noticed the QR code floating in the air. That's a part of a bigger in-game mystery, functioning as an introductory gateway. That QR code hints to players to enter the game at midnight. I won't spill more beans.
As for the plot progression, ending 2 doesn't really resolve the problem with the monster. After all, if as a player, you’re wandering around an equipped device blatantly, how could the monster possibly miss it?
