It's ok. One of those standard grind a job to buy items from a vendor so you can give gifts to an NPC to raise relation enough to unlock scenes type games, but very early.. and a bit juvenile.
As far as sandbox type games go it's not the most annoying, there's no gratuitous room navigation or anything, and the grind isn't too bad, but it is clearly time padding for a game that only has a handful of scenes. It's also quite rough in that it pretty much just drops you in with no prologue or intro and just tells you to meet 10 people, who for some reason you don't know despite living in a vault together. I guess you're supposed to be a new resident, which doesn't really make any sense in Fallout lore, and the game makes no attempt to create a fan-canon to explain it or really anything else.
All in all, it's a pretty shallow hentai parody of Fallout, with characters who are right off the bat completely horny brained with the very first girl you meet flaunting herself and the overseer having giant hyper balls because he's a no-fap god. It's all pretty corny and juvenile, don't really expect any interesting writing here about a unique vault experiment with complex characters or anything.
That said though, once you get over the horn braininess of it, Diana is a pretty hot character, and her horny teasing dialogue can be fun. I like that she's more just a confident minx rather than a femdom. She's essentially the only character with content at this point, so it is good that she's at least hot, even if I wish it wasn't quite so blatantly on the nose. If any other characters have content, I wasn't able to find it.
As for art, it's better than average AI use and maintains a pretty consistent art-style and character appearances (which are refreshingly gritty looking and not more cartoon pipboy shit), and I noticed no obvious AI anatomy slop. But, it does appear the dev is still bottlenecked by the difficulty of multi-character scenes that all AI by itself struggles with. The few sex scenes it has already have a recurring issue of it generating anal scenes when the dev clearly wanted somethin vaginal from the dialogue. I hope they're able to up their game with some Controlnet usage or something, as it's going to need it as the game moves out of just teasing content. Since the scenes are also just a single image, giving them some slight animation with Live2D or another still animation tool would add a lot of much needed pizazz too.
As for the engine, I see no particular reason this needed to be made in Unity, and the lack of any options screen whatsoever to adjust text speed or volume is definitely an annoyance. They're gonna have to reinvent the wheel some to get basic features that come stock in renpy.
All in all, still a very early game, and a very simple one, but it does have some potential once you accept it for what it is: a horny-brained soft-sandbox trainer-style Fallout parody with AI CG. Not quite my cup of tea as a genre, but definitely not the worst one of those I've played either. If you're the type that fills your Fallout install with horny mods, you'll probally enjoy it.
