So a couple of notes playing through 0.2.1 as a new player:
This game, at least as it stands, is obviously a slow burn. It doesn't just jump into the sex. It doesn't (again, as it stands,) use sex as a plot point for the player character like most erotic VNs I've seen, which I can respect. And aside from a shower scene and some spicy pictures you get at the very tail end of the update (unless I fucked up a choice somewhere), there's very little in the NSFW region so far.
The way to move around between locations is fairly seamless, aside from clicking around inside the house. The backgrounds look lovely, and the overall ambiance and lighting are amazing, though one thing I noticed is the distinct lack of music playing outside of conversations and cutscenes. Which while it felt strangely jarring to going from no music to suddenly having what sounds like generic atmospheric piano number 1, it's not so much of a turn off that I would quit playing.
The female characters are beautifully made and extremely well written. There's an obvious amount of depth to the girls so far that can be felt just by talking to them in cutscenes and learning of their problems and traumas through storytelling; Natsumi's abuse and need to put others above herself, Kaede's need for self acceptance, Hana's want for attention, the principals need to be in complete control (or for dick I can't figure out which). Though I wish the dev had gone more in depth with the other side of Nova's coin that causes the player to be more "chaotic".
The only problem I have so far is that the player character feels like they're going out of their way to be an unlikable dick. Almost like he just took a job in psychology to not do, y'know, his job as a psychologist. And his inner monologues reinforce that. I'm not sure, but his disdain for what he does just feels kinda forced instead of being naturally socially awkward in their own way.
In short, the game so far is amazing. The art, the style, the writing and feel are very impressive. And tackling issues like mental health in an erotic VN, while I'm sure has been done before, makes for a very different and unique story. The only thing I ask, is make the MC not necessarily likable, but at least more relatable or tolerable. Solid work dev, I will be watching this game with great interest.
