(Review is for v0.9.1)
Actually incredible.
The renders start out shaky and the game starts out with a really annoying amount of sound effects and not the most convincing story, but it very steadily improves from there and you don't have to wait long for some very hot action. In the later half (more like later 70%, it really doesn't take that long to get good) the models become actually top tier, the animation ranges from acceptable to fantastic and the sound effects start being used smartly and to accentuate certain scenes rather than be a repetitive annoyance. I have to say, while this game doesn't have overall the number one visuals out of all games on F95ZONE, it actually does have the single best render out of any game I've ever played on here and it's of one of the girls in a particularly fancy dress. I damn near ejaculated and had an aneurysm at the same time, I promise you I have never seen anything so hot in my entire life.
As for the story, the MC is very, very much a power fantasy figure where pretty much everything works out and he gets (almost) all the hot girls he meets. If that's a problem for you then probably stay away, it's a very big part of this game, but personally I LOVE IT. This MC basically makes all the same decisions I would have made in his place so it's exactly the kind of fantasy I get on here to play, humongous props to the developer for getting this kind of power fantasy down so damn well. FURTHERMORE, the story beyond the MCs power fantasy is really, actually very engaging. I don't usually get into the stories of most of the AVNs on here and skip through most of it to get to the sexy bits because they're not written well enough for me, but this one really is. There are probably not even 5 games on this website where the writing has actually managed to make me genuinely care about a male character other than the MC, but this one does just that, and SO much more. I get so incredibly engaged in the stories of these girls and their reasons for wanting to be in a open relationship with you, or the other characters you meet along the way and help or put a stop to. There's genuinely only been one girls so far whose writing was a little cringe to me, but it was a bit funny to me instead and I can forgive the game that. Not every little thing can be a slam dunk, at least not with everyone.
I see there's been some rumblings about NTR and/or sharing and let me put my perspective on that, as someone who absolutely CANNOT stand NTR of any kind and I've dropped more than a few game over this. This game does NOT have NTR. It DOES have sharing but only with other girls, and most of the time you can skip that (maybe all the time, I wouldn't know, I love seeing my girls share each other, it just makes harem games all that much better).
BUT!...
What it does have is the *threat* of NTR, or more accurately r*pe or assault. Without going into much details there are several times when dumb assholes are trying to get handsy with your girls, but it's only so that the MC can give them what they deserve, which just plays all the better into the whole power fantasy IMO and actually improves the game. No one is ever truly stealing one of your girls. ALSO, there are several really quite hot girls that (at least so far) will NOT be your girls but trust me, there are MORE than enough girls already falling at your feet that you won't feel too bad about it.
In short, I just can't recommend it enough. Give it a shot past the first wobbly chapter and maybe a half, and give the story a genuine try if you're the least bit into it and I really don't think you will be disappointed.
