This a very good first installment of a game.
The premise is pretty good, it gives a good reason of why your father is dead (like many other VNs do in a much more "handwave" way) , while giving you a connection to him and your mother already. There is potential for conflict with the mother when/if she wakes up, there is already something for the characters to overcome (the grief of the loss and the matter in which it happens) and it does a good job to justify why a teenager is suddenly the boss of a gentlemen's club. All in all, great setup for the game.
From that point the story starts to evolve in a very believable way, the characters have lives that do not turn exclusively around the MC, they have friends, boyfriends, wants and needs and clear personalities. We do not get to see much of any character, but we aren't introduced to dozens of them either, the 3 sisters, 2 friends of the elder sister, the lawyer, 4 employees of the club. Not all of them get the same screen time, but you already get to see their different personalities and the seeds of different storylines are planted here. There's also some girls, guys, and even organizations more or less shown through friends/rivals in school and how they behave.
I particularly hated the boyfriend of the elder sister and his jock friends (whom we do not get to see). I think it is a good decision by the dev to show that your sister hasn't let him in her pants yet, hopefully we will have a say on that and decide whether we want him involved or not.
The renders are good, the girls all look like real women, none of the balloon breasts, but proper feminine shapes. Hopefully we get also a variety of pubic hair (please, not all shaved....) . The lightning, composition, transitions.... etc are all competently made, and the animations are great and fluid, including some dances that are very well done.
Talking about transitions, one thing that is very well done is the passing of time, you get little messages with the date and time when there is a jump of scene (I hate when VNs do not give you any time info and just jump around) . This is very well done, grounding you in the world and making it more realistic and believable.
I couldn't see any grammar mistakes and the conversations between characters all felt natural and how real people would speak. I have seen someone talking about how the characters do not show enough grief and the devs explained that people react to grief differently. Having personal experience with this kind of trauma, I agree with the dev here. I think the characters are a bit in a state of shock and trying to behave normal but there are hints of grief and how they behave in certain ways shows that they are processing it. We will see how this is handled further on the VN but so far I found their reactions believable and human.
There are a couple of sex scenes and they were very well done, I would just have liked some more control over them (for example whether to creampie or not), we will see if this is done in the future.
I also really like the fact that there are numerous potential LIs with different degrees of lewdness, you can have a clean, loving relationship with some girls (like the friends), an incestuous relationship with your sisters, a domination relationship with some employees and schoolmates, you can share or pimp some girls while keeping others for yourself.... none of this is yet in the VN but the setup for it is already there, which makes me really look forward to future updates.
So, overall, a great setup and very well executed, total 5/5 for now, hopefully the future keeps being this good!
