Hi there! Thanks so much for trying out both the original SU and this parody game. I tried to make npcs remember choices but honestly it's getting a bit out of control, so I need to organize it better in the future lol. But it is important to me for the characters to behave as appropriately as I can manage. I am excited to read your comments and inquiries as I'd love to get into a deeper discussion about the world building. To answer some of your questions, there might be spoiler stuff ahead:
SPOILERS:
Two factors keep Ilyon from understanding what/who "Noctisse" is in the parody.
1. One of the things that Ilyon discovers in the "void" in chapter 4 of SU is that although there are an infinite variety of variations of realities, 'threads' or the essence/composition of existence remain constant across all realities. The question becomes how much can realities differ within these parameter and are these differences ultimately meaningful? Technically 'Noctisse' on a 'thread' composition level is the same as she's always been.
2. Ilyon has always had a game of cat and mouse with Noctisse. He wouldn't normally dare 'analyze' her threads, as she would normally be able to detect this and find it intrusive. It's only after he's suspicious enough of her that he dares "probe" her to discover that she's let down her guard/awareness and something has truly changed. This is when he begins to approach her in her dreams, since her thoughts are more transparent in her subconscious.
