There's something very steady about this game which makes it fine but the more I sit away from it...after doing all the endings...the more I feel like it was a game that went through the motions with some interesting concepts but just felt rather emotionally flat. Which isn't great when you are playing a visual novel since you don't really have other things you are doing to engage you. In a sense I'm torn between rating this higher and lower and ultimately settled in the middle because

Things I liked
-Presentation in terms of visuals, animation and sound effects. they definitely spent budget here. voice acting also excellent.
-Chapter pacing. No chapter felt overly long.
-Not "redeeming" a character just because they are supposed to be on the "good guys" side for the most part.

Things I disliked
-Without saying too much, half the cast, even in their own routes, don't feel really developed. I only ended up caring about one of the 6 girls. 2 were developed okay but I didn't care for them. 3 did have their stories but it also felt like they were there for the count.
-The true ending. I did not like it. It doesn't help that I didn't like the girls' routes that much, except for one.
-Just in general. Like I didn't hate the creepiness of the otaku main character but it also really didn't feel like it had a point emotionally.

Funnily enough I liked the "worst" of the endings the best. Maybe because that's just how I saw the protagonist.
