the title itself is pretty ominous - especially with the warnings at the beginning. the narrative is very mysterious -- the options given with a lack of context make it even more so. some of the options given also feel very ominous (concerning the character's backstory). idk if in some/one storyline it's clarified a bit, but it makes me very curious! :)
the day/night background switch helps a lot with pacing? it gives a better sense of time passage (and in general visually fits the ongoing narrative).
the only issue (not really an issue -- it's super minor) i found was a formatting error with the italics. i wish i remember where exactly it was, but it was in one of the daytime passages.
very tiny suggestions?: for the daytime maybe use a bit of a less-white-white? it could 100% just be me (light sensitivity). also some of the images were a bit jumpy for me (i think they were re-loading each time). idk what method you were using, but i had something similar happening when i displayed a different passage within the passage -- i switched it to click-replace and it stopped (but it also had no images, and it also made my passage & event-map kind of confusing to look at).
