I'm just some asshole who just finished playing this game. I usually don't give my opinions because A. Who cares what some asshole thinks, and B. I don't care what other assholes think.
That said. I want to give my opinion on this game.
First the characters. I must say, I have a serious type. Which honestly leaves me not caring, or generally hating the majority of the characters. Plus, the male characters in adult games I dread when they appear. Mostly because I figure I'll hate them or some NTR crap will happen and I'll hate the game NTR is a crap fetish, dev don't make any NTR unavoidable.)
The characters in this game however, both male and female, I generally enjoyed. They all had unique personalities that come through the story, which sadly I feel most games fail at due to poor writing or bad English translations (most of the time a mix of both). Although I feel the "lonely" mother thing isn't very pushed. I feel as though she may be the most bland character.
The story itself is great. I really enjoyed it. I was heavily disappointed (in both good and bad ways) when I finished all content in the current release. I don't know if I'll play the other specialties routes, mostly because I don't feel like they would add to much to my experience at the moment. Don't wanna be disappointed by that "thanks for playing" screen again.
The gameplay is sorta... Non existent. It's more like a visual novel than a sandbox imo. I believe placing currency and stats would at least give some gameplay as long as it's not super grindy. Finding items can be a real pain in the ass. I struggled to find the notebook, even after the sisters hind and reading this thread for it. I couldn't see any indication that it was there at all. I had to furiously click around it and eventually I got lucky. Some items, like something I saw while looking through this thread for the notebook, I didn't see any hints about it. Unless it revolves around a specialty a didn't select (I chose fitness).
All in all, I enjoy it immensely. I'll be following it and keeping my fingers crossed the dev doesn't get "the sickness".
