Thanks for commenting! I hope you don't mind me defending the game a little bit.
1. The difficult thing about these early story-driven VNs is that most of the components won't make sense until later in the game. Flashes, sure I'll give you that, don't make sense in the setting yet. A lot of the stranger elements early on are intentionally set up without immediate context because the story is built around delayed payoffs and reinterpretations. What doesn't make sense now, either stylistically or metaphorically, will only make sense later once the broader picture becomes clearer.
That said, it is still a fair criticism, even if it's something intentional for the long-term. Flashing imagery has become very common in this market, so I understand where the irritation comes from. But in this case, these elements do tie directly into later plot points, so I can't dismiss them quite yet.
2. Sure, fiction cannot solve all those inconsistencies, but I'm also not promoting the game as a completely fact-driven story either. I mean, there are no trains from Seoul to Japan, wills are to be given out to beneficiaries after death, and there is no such thing as a nationwide Flunk program instated throughout all of Japan. The world isn't meant to function as a perfect mirror of reality.
Obviously that doesn't mean hiding behind the wall of "oh it's fiction" makes it okay and excuses everything. I do a lot of heavy research on topics for that reason, as evident from the Faust/Goethe scene and several others (I learned a lot about Japanese dodgeball and how weird it is just for that one scene). I do care about authenticity and accuracy where it matters, but sometimes it is necessary to bend reality slightly for the sake of narration or thematic intent.
Sorry for the essay. Thanks for playing! (:
