Small details really made this one for me and the beginning paragraph/lines really got my attention. I can't help but to "explore" every option you made, aka click everything that is clickable, and I really liked how some of them were just for fun and setting the mood, like in the elevator scene for example. Bonus for pacing too, some impactful moments were there. I think I would have liked to see more visual variations, even if it was just placement of the text and maybe some sounds/music to create mood or make each "flip of a page" so to say have more impact, but I think this can work like this too.
Overall I liked it, the ending I got first was somewhat dreadful but still sweet, pretty bittersweet I'd say. Nice work. ^^
