I normally write overly lengthy and verbose reviews. I'm gonna be brief (for me) with this one, because if I go into detail it's going to make the game seem worse than it is. I've read some of the dev's comments here, and he seems like a nice enough guy that's trying to do something he enjoys. I don't really want to be too harsh, but I don't think disingenuous white lies will be useful for potential readers nor for the dev in creating great VNs or kinetic novels going forward.
I'll start with the positives: The girls are cute... physically... if you like redheads with freckles, as the entire cast of LIs are gingers. I'm not really into freckled reds, but still they're attractive models. Even if I do usually like them even curvier than these three, they certainly aren't twigs by any definition. Next, I liked that the MC is neither a pushover nor an angsty siscon. I mean he's definitely a siscon, but just not a nervous guilt-ridden wuss about it. That said, the pendulum might have swung too far the other direction here. Him being some kind of badass, jacked, preppy-when-not-shirtless street tough that lives in his parents' very nice upper-middle class house when he's not rescuing redheaded girls from would-be rapists clues you in that this is going to be a Gary Stu fantasy. Apparently, other than cringy banter, that's his deal. He hangs out near alleys after school in case a redhead is being sexually assaulted, so he can deliver his signature surprise head kick to save the girl. Finally, I like that there's another underlying (or overarching?) plot involving organized crime and corrupt police. It's not a unique feature, but we've all played games where the only point is to build a harem by saying nice things to earn love points until MC can get a handy, then a beej, then sex, then anal with 15 different girls, so I'll give credit for having an actual story. This game's other plot doesn't take center stage often, but it's integrated with the rest of story throughout. It's most importantly invoked as an inciting incident to "get rid" of his parents (i.e. get his redhead sisters alone), to move the cast to new locations, and occasionally to remind the reader that the MC is, in fact, an alpha-as-fuck badass gangsta muthafucka... as well as a loveable softie with an epic cock and sub-7% bodyfat.
The negatives, which I've already hinted at, are the plot and the dialogue... oh and a noticeable number of the renders could benefit from denoising. The plot could be good, but it needs an editor. Not because the grammar, spelling, or other technical aspects of the writing need much work. It needs an editor because dev needs somebody saying, "These plot twists are too abrupt or unjustified", "This character's behavior is inexplicable and unbelievable in a world without high-fantasy, sci-fi, or other excuses for bizarre behavior", "There isn't enough information or foreshadowing for this part of the story to make sense to people that aren't privy to your unwritten head canon", or "That random plot twist that made no sense and needed more explanation at some point: remember that? Yea you forgot to explain it, like... at all... ever. You just forgot about it and rushed into a bunch of epilogue sex".
However, the biggest and overwhelming problem I had with the writing is without a doubt the dialogue. I wouldn't say it's always cringey, rather it vacillates between cringey, irritating, and tedious an inordinate amount of time. I like banter, teasing, and witty dialogue. Many games are woefully dry in the dialogue department. It's hard to get right, and few excel. This one fails hard. The banter is damn near constant, which can be done to success as it is in Dr. Vibes, but it has to actually be funny and clever for that to work. The ball-busting from the twin that talks needs longer breaks to keep it from getting tedious. Then there's all the Gary Stu dialogue about MC being their "king" and how he's the only man any of them have ever wanted. Reading that stuff once or twice is good, three times is okay, but it comes up a lot more than that. There's a so much time spent telling each other and the reader how much they all mean to each other. It's too damn much.
It would be a 2.5 out of 5, but honestly it was enjoyable as long as a I didn't think much about anything or expect satisfying explanations for any of it, so I round up.
