I was interested in the game based on some teasers I've seen on discord but, after playing it, I don't think it is for me.
The "unique" (the non-human girls) character designs that got my attention weren't enough for me to enjoy the cast.
It is very evident that a ton of effort was put into this game, and I don't want what I say below to take away from this. The game looks very good and is vastly superior in many ways to most other games that get released here, especially in their first release.
So bear in mind that what I say below is my own personal assessment of things based on how I, as an individual, tend to evaluate things. Your mileage may (and likely will) vary.
The aesthetics are not for me. They might be exactly what some folks are into but definitely not me. Nearly every girl (even non-LIs that are shown naked/fucking) have pierced nipples and/or tattoos in varying degrees (one character has basically her entire body tattoed, another have "Daddy's Girl" tattoed in her face, right below her eye among many other tats) and/or septum nose piercings (aesthetically the worst one out of all nose piercings).
In short, many of the characters' looks scream "corner prostitute that goes for 5 dollars a fuck, 2 for a blowie".
So that alone already make me not invested in most of the cast, and with it, the game. Then there is the backstory of some of the characters, at least one of whom has that good ol' and "beloved" (recurring) rape backstory.
The game's setting itself felt strange to me in the sense that there is a lot of hornyness present throughout the story that didn't mesh well with the tone and timing when those sexually tense moments happened.
So far, I think this game might've been better with a female MC focused on the yuri. As things stand now, I feel like many of the things I enjoy in games with the tags that this game has clash within itself. For example, there's a clear setup for a harem in there, but I'd say the majority of the harem fans will not like THIS harem (and I'm not even talking about the ultra tryhard ones).
So I guess if you enjoy the "tattoed chick with piercings galore" style, enjoy (or at least doesn't mind) lesbian action in spades and don't mind "dirty" and "used up" backstories and pasts for the characters, you'll enjoy the cast.
I can't comment fairly on the story as I abandoned the playthrough midway through it after checking through the cast of characters and realizing I don't like the vast majority of them for one reason or another. I played through around half of the game before fast forwarding to the end just to see how much content was left and what other characters I'd eventually get to meet. If I liked what I saw, I'd continue the playthrough normally.
So with all that said, it's also evident that the dev put in a ton of effort in this, and the game is very decently polished - especially considering that this is a first release. Some of the criticisms I've seen in the thread I felt were quite unfair, like the use of the "cultivation" setting with characters that have japanese names. That to me is a ridiculous criticism, as a setting can be used in any way, and the dev mixed a bunch of different elements in here - there's even some sci-fi mixed in there and the use of grenades. If the dev was successful or not in mixing all those elements is a different conversation, but criticizing things like that just seem petty to me.
One particular criticism I find ridiculous is complaints about Aya calling the MC "not-brother". It's clearly a part of her characterization to call ppl names and ONLY SHE uses that term, mostly as a means to annoy the MC playfully (she's a bit of a brat). She also calls Noriko not-sister and uses other dumb names. It's fine for you, the player, to not like it but this is the way the personality of this character was built. It's not a knock on incest, or a signal to credit cards companies to turn a blind eye. If anything, it's a not-super-subtle way for her to remind the MC that it is perfectly okay to give her the D, just in case the MC hesitated in doing so because of his up-to-this-point fraternal relationship with her.
Other criticisms I've seen made it clear that the person making them hadn't actually tried the game. That's hardly fair.
One other note - the dev said that there is around 2 hours of content in the game, I believe? I think that's not very accurate - I'd say it's more. I think 3 hours give or take at average reading speed. It's a pretty chonky first release, and I can only see that as a positive. If you enjoy what's being served, then you'll have a feast,
So I hope the dev is successful and finds his audience. Unfortunately, I think I'm clearly not part of the public that this AVN was aimed towards.
Best of luck!
