thanks for your very useful feedback & glad you had enjoyed the VN!
the ending is kind of in a weird state because a lot of the research i did was ultimately left out for pacing reasons, particularly about the (fascinatingly mixed) reactions by the residents of the area since 2009, so you're right that the explanations feel sort of extraneous. it's an awkward middle ground that it might be possible to adjust to either direction. (in my mind, the character drama relates some of the cut stuff, but i'm fine with the specific authorial being impenetrable in the final product. i wanted to leave it somewhat open to interpretation to respect the different thoughts & feelings people have about the real-life events and the current status quo.)
also, re: your writing nitpicks, i'm not sure how apparent it is, but the translation process was pretty hasty and i honestly just forgot to check that the date formats were consistent in my hurry to get everything done. i'll take care of that after the jam and look into the kinds of clarity adjustments you mentioned as well.
the skipping stuff happens because that portion is implemented as a "cutscene" internally, changing the behavior so that you click the button once to skip the whole thing. this pausing skipping is a half-intentional side effect that probably feels more confusing than useful on the whole; i'll look into changing it. a slider for skipping speed should be easy enough to add, just haven't done that yet.
