This review comes with a major caveat that I have NOT played most of the game. Nevertheless, the beginning of a game or story is just as -if not more - important than the rest and I just couldn't get into this one. The art is fine and the UI is easy to use, so credit where it's due. Unfortunately, this is a VN, and VNs come with their own challenges that this failed to meet.
With the exception of the sister, all of the characters I've met so far have been utterly unlikable and rude. The MC gets consistently walked over like some shitty, blubbering anime protagonist and the story railroads you into putting up with them. There are points where you can choose between a dom or sub sex scene, but then it's right back to being insulted for no reason. I usually try to be objective with these kinds of things because it's usually a kink, but at some point I have to find something likable about a character - a hot bitch is a bitch, but at least she's pretty to look at before she stomps on your dick. Here, there's nothing but perpetually off-putting characters.
The writing is sub-par and gives major whiplash. "My sister just teased me for having a small dick when we were kids! I know, I'll whip it out and show her what's what! That'll be funny!" This is then followed by the main character giving a Patrick Bateman "I'm empty inside" speech and lamenting the deaths of his parents. Which is it? Am I supposed to be laughing along with a writer that's self-aware of how ridiculous this is? Because it seems like they're playing it straight half the time, which means the characters just appear incredibly cringe and socially inept.
There are other missteps in how the game presents content and characters, like the MC vehemently refusing to sell a lewd video of his sister and acting clearly disgusted by the thought of sexualizing her, before waltzing into her room, sniffing her panties, and stealing them while gleefully exclaiming that he intends to use them to masturbate.
So the writing isn't great. But there's another aspect of making good VNs, and that's choice. Early on I thought there was some clever decisions going on, but ultimately there is no meaningful choice because there is no "fail" state. In an early quest, you can interrogate a store manager and the clerk. The clerk was hostile in early interactions, and so when given the choice to stare at her breasts I did not, opting to simply ask some basic questions. The older manager, however, I did stare at. She appreciated the attention, as I thought she would from the hints the game gave.
None of that mattered, though. It's an illusion of decision making - whether I was an idiot or not had no bearing on progress with the characters or the quest in general. To drive the point home, I could not leave the scene despite exhausting the options for asking questions about the case. I finally went back to the clerk and remembered that I had chose not to ask what seemed like a pointless question: "Do you like parties?" This turned out to be the MC making a bizarre and baseless accusation against the clerk, angering her. However, after doing so I was allowed to leave the store and continue with the game.
I will probably play more of it after a break, but the two hours or so of playing were such a turn off that I'm only considering it out of fairness to the developer. If I change my opinion, I will update my review accordingly. For now, I'm giving it a 3/5. The game looks good and it isn't a pain to play - that's the bulk of what goes into making a game and the dev has done a great job there. If they had somebody go through and rewrite the thing I could see it becoming exceptional, but ultimately it's "just another VN" of the caliber to be expected from amateur creators.
