Tl;dr: Believable slow-burn netorase story with beautiful, curated and consistent AI CG, fantastic dialogue, likeable characters - not for impatient coomers.
Let me start with this: You can kind of tell by the ratings this game received, that you'll either love this game or dislike it, there doesn't seem to be an in-between. Now, you can also tell that the vast majority does in fact love it. And that the only people criticizing it, do so mostly due to the fact that they have to read a lot of dialogue or that the transitions spook them when they CTRL-skip through the dialogues. There isn't even any typical and expected AI CG hate, it's really just people complaining about either not liking the premise of the game (fair, I suppose, but why play it then?) or just nitpicking the most mundane stuff, sometimes straight up lying.
With that out of the way, let me summarize why this game deserves the praise it is getting from most of the sane people on this site that are not opposed to NTR/NTS content (you really don't have to love it, just be open about it).
First and foremost, this is a well written story. That alone elevates it from about 90% of the infantile, incoherent and illogical plots games on this site have to offer. Now, this might be irrelevant to some of you (see above and evaluate for yourself whether you are a coomer who only cares about boobies and find any form of text annoying), but if you belong to the section of users who like to immerse yourself somewhat into the story, appreciate natural and believable conversations, a decent pace and personalities, then this game will be for you.
"But it has AI CG, it is stealing from real artists and it's shit and they have 6 fingers and I really hate change and wish to live in the past forever!" - Stop it. Yes, the artwork is based on AI generated images. However, the dev is clearly very talented and diligent and has not only, I assume, created detailed LoRAs for each characters that support the visual consistency of the characters between each image, but also manually fine-tuned the images, improving the quality and exterminating any immersion-breaking factors like unnatural anatomy, improper artifacts, anything of that sort. Of course, if you have seen a few of those AI generated Anime pictures in the past, you will most likely recognize a vague art style prominent in such AI CG due to the source material fed to the models, there are some distinctive yet still subtle features about it. However, it still does not break immersion or look weird, quite the opposite, they genuinely look fantastic. I am convinced that if you were to show those images to someone who has never looked at AI generated Anime pictures before, they would be none the wiser and I assume all those are hand-drawn by a skilled artist. There are very few artists that are really capable of providing a better quality than that, the likes of Teku maybe.
I already mentioned the plot, the decent (by which I mean slow and authentic) pace of the story and the authentic and likeable characters. They are not caricatures of run-of-the-mill porn-logic protagonists like in the majority of games featured on here.
I personally prefer a confident and dominant MC, it's just something I identify with more and which makes it easier for me to immerse myself into the story. In this game, the MC is quite insecure, shy and rather passive. However, he is not a stright-up wimp, he has facets to his personality, he is possessive and not oblivious of his flaws and is genuinely not just a dumb idiot. Likewise, his girlfriend is not just a dull nymphomaniac that is looking for a way to cheat on him, they in fact have a loving and complex relationship that is portrayed in a believable and, dare I say, wholesome manner. The transition towards NTS content is slow and careful, yet not glacial, it introduces the ideas and plants them in both their minds simultaneously, allowing them to process them openly and on their own terms. Things get more and more heated with every encounter, despite some other commentator claiming otherwise, there are some spontaneous and rather unforeseen events happening as well. Also, the teasing by the GF is some of the best you will see in such a game, it is really masterfully crafted.
There is currently also two other characters, the male "third wheel" who looks like the typical, as one reviewer called him, "big dick chad gym bro who is destined to fuck the GF", but who is actually written like a decent friend who acts natural and authentic, not feeling like a shoe-horned attempt to use him as the object of lust for the GF (even though I guess he technically is, but duh - still doesn't really make it less authentic). The childhood friend is a catalyst of some sort, raising the open-mindedness within the friends group and poking the stick into the firepit (?), trying to stir up the dynamics between them and make everyone realize their true desires.
All in all, it is a nice cast that compliment each other and that have a nice and believable dynamic. No "There are 17 LIs that you can choose from and form a harem with" bullshit (no offense if you are into it) but just a bunch of friends trying out new shit and seeing where it leads them.
Again, this might not be your thing, and that is fine, I saw that people say games like BaDIK have a shit story and unrealistic characters, so opinions may vary (and be shit), but I genuinely feel like there has been some thought behind the characters and how they interact with each other and that is something not every dev is capable of creating.
So unless you are someone who is really just looking for a quick 5 minute wank or you cannot stand NTR/NTS content and jump off your seat in anger the moment you see someone other than the MC just glance at any of the females in a porn game, you really need to try this - now!
As of version 0.4.0 it has already a lot of content, I see the dev is touching up some of the CG still and adding animations (which look good, despite what some here said, bouncy tits are a heavenly sight) and is in general passionate about this project. I usually wait for games to be completed, or at least for significant upgrades, but in this case I feel tempted to follow the process more closely and check out new versions regularly. It just really left an impression on me.
The NTR/NTS genre already has a lot of mindless games that are essentially power fantasies that read like they are written by horny teenagers, being sexually educated by hardcore porn, with one-dimensional characters, using the same Koikatsu models like 60% of games on here, but still get hyped and praised to Heaven (looking at you, The King of Summer - no offense to the dev who is doing a great job and updates regularly).
I just implore you to give this a try and help it receive its deserved praise and attention.
PS for the dev: The only suggestion I might have for the dev is to consider the idea of implementing a mobile phone or similar function, given that the MC already texts regularly, I imagine it could be a cool way to implement those conversations more naturally into the game, also having those conversations/photos available to re-visit. I know that much less talented and ambitious devs were able to code something like that, so hopefully it wouldn't be too much of a bother. But I do believe that it would improve the experience for the future too, assuming there will be many interactions between the MC and GF when they are not physically in the same room. Plus a nice way to implement basic game functions, save/load, gallery, etc. [insert Marge Simpson "I just think they're neat" here]
