I'm still confused as to why this is "the darkest chapter" or whatever? Like I get that Sensei is mopey and Ami is in a bad way, but just telling us over and over how bad everyone feels doesn't make it dark. To me, Chapter 3 was far and away "darker" than this chapter, and unless something changes (which would involve actually moving the plot forward in any meaningful way), I'm not sure its going to rise to the level of previous chapters.
I agree with the above post about feeling like this update was phoning in an essay right before the due date. Writing was low quality by this game's standards for most of it, the 4th wall breaks were most certainly the worst they've been yet, and I had to mute most of the dorm wars because the music did not fit at all and was super distracting while trying to read.
I'm glad that some people at least enjoyed it to some degree, but I was incredibly disappointed, sadly. I want this game, this story, to succeed and be great; right now, its just not. To me, at least.
