I just tried out the game, by curiosity, but I ended up almost playing through all chapters in one session. (Of course, I didn't just speedrun the game...)
I didn't get to play it until now, probably scared off by the heavy topics warning, and having a lot on my mind lately.
However, I think this heavy topics warning is kind of insignifiant in the game. I'm not saying the warning isn't needed through...
I honestly got flabbergasted by this VN, in more ways than I can probably figure out. Sure, there isn't any paths/choices in it, compared to every other VN I played. But seriously... The ambiance, the backgrounds, the music, the characters...
WARNING Spoilers ahead
Most importantly: The combat scenes !!! They're just so unique and epic.
I love every details of this VN and can't wait for the next chapter !
