Very interesting. I think this kind of interactivity is something that should be explored in traditional stories so it's really great to see someone finally give it a go (personally I struggle to follow characters and such, so being over to hover over people to remember who they are would be nice in longer books).
I think the "story" works well with this kind of mechanic as well, going back and finding out about the other people there after knowing what happens has a strong impact.
With that said, I don't think the pacing is great. As in, through any play style. Play without reading everything, it abruptly ends after 2 pages. Play with reading everything, it abruptly ends after 2 pages. I know this is where the "but that's the point argument" could pop up, but more than anything it just left me underwhelmed.
Perhaps if after going back there was more story to unfold, but it felt far too ramble-y after a while which isn't a great note to end on. More like padding than anything.
It does raise a lot of interesting ideas though. Like, what if you go back and reading in more detail re-contextualizes the events.
But my biggest complaint was that you basically had the opportunity to do so. Instead, we get the ending ramble telling us what the stories about. No story should have to end by telling the reader "this is what the stories about, this is what it's meant to make you feel", that's the stories job. Going back and reading everything else might have had a lot more impact had the end screen not literally gone "this is what the story is about", isn't the entire point of this that I can go back and discover that for myself, instead all of it was spoiled. At least give the option to play again before proceeding to developer commentary.
To end on a more positive note, I'm glad this sort of thing exists. There's so much more opportunity for discussion in a story that people experience at different paces and where they know different information.
