The site didn't let me post my essay of a review in my rating. So, I'll post it in the comments instead...
3 STARS This could have been a 5 star game, but the ending was rushed a many opportunities weren't pursued while dropping almost all of the fetish content that most people downloaded it for to begin with. To be blunt, the romance is bare bones. That's fine, if it's serving as a backdrop for the fetish content, but when that's no longer at the forefront it simply isn't enough to carry the game as a whole. While I would have LOVED a Bad Ending where the protagonist and all of her friends were stripped, spanked, diapered, pegged, broken, and enslaved with her romance still existing in a twisted form bonding over their mutually shared doom, that's a matter purely of taste. It would purely be a bonus anyways. So, that and the fact that I personally would have loved to see some full on pornographic content are both not things that impact my scoring in this particular review. Rather, it is the missed opportunities that really hurt when the first two chapter's had set up both plot hooks for them and the expectation that we'd receive scenes to the degree of those chapters. I did believed in that potential to have become a Patreon subscriber. Just going off of what I expected to see. I expected to see Zaza and Sophie to get a severe punishment after failing to defeat Marion, especially after the hilarious moment where Marion actually blocked the bullet. Then I expected to see Genie save them both by having Castyxo fight, defeat, and subsequently punish Marion with some combination of every punishment given to Zaza throughout the game as an epic finale. Instead, I got excited only to be denied. The humor is great and the animations themselves are truly fantastic. Had the last chapter been at least in line with the quality of the others and still rushed the plot, I would have still rated the game 4 Stars. Because of those previous chapters and the lack of a price, I am rating it as 3 Stars, but the last chapter itself is just 1 Star. You might be wondering why I mentioned that this could have been a 5 Star game at the start. Well, that comes down to the things that could have been done to exceed my expectations without even crossing the line into a full on pornographic game. I hesitate to cover the writing improvements that could be made, because I fear that your more interested in writing a romance than including the animations that I came here for, BUT if you have read this essay of a review all the way to this point, then I suppose I should start with opportunities you'd probably be more interested in. For the theme of Magic VS Technology you had a good start with what you were setting up, but you either didn't realize why that was the case or you just fumbled it at the end. When Zaza revealed at the start of the game that Marion is a highly respected mage despite it being considered a dying art, because she was such a skilled practitioner of the craft and followed it by Sophie making the argument that ANYONE could replicate a significant portion of Marion's abilities through technology, you had set up an excellent metaphor about the relationship between highly skilled labor that can only be done by an elite few with the education and resources for it and "good enough" products that allow common people to replicate those feats. You could have had it be reveal that Sophie's parents really did massively improve the life of many commoners in how they made their fortune, because there are only so many mages and all of them have to charge a high price for their services even their services are able to cover areas that technology alone cannot. That would add a much more interesting reason for Sophie's ego about her position and the technology she's associated with. Conversely, magic itself can be considered a good thing as well by showing, as you did in the ending, that there will always by some things you need a highly skilled specialist for. This and Zaza's sheer determination to learn to level at which her services could be worth riches despite literally coming from rags could have then reminded Sophie the reason she thinks technology is so great. That being that it enables even people like Zaza who have no resource and no skills, but are willing to suffer for their dreams. By embodying that Zaza could have gotten Sophie to have fallen for her beyond, "Oh look a girl I think is cute is getting spanked and I know that I can convince her to let me spank her too." The ending could have then (after all the fetish scenes that SHOULD have been there) been Zaza deciding to work with Sophie to invent Techno-Sorcery. It would have had an amazing moral about old art forms still being valid while also encouraging innovation not letting yourself be taken advantage of while pursuing your dreams. Now onto the fetish stuff that would have gotten 5 Stars. I would go into detail about all the pornographic and fetish content that I would have loved to have seen, but I doubt you are willing to get that lewd and this review is long enough anyways. Instead, I will compromise and list a few different kinky endings you could have had as "bad endings" in addition the the "True Ending," that I proposed where through the power of friendship they get Castyxo to completely dominate Marion and Zaza becomes a Techno-Mage. 1 Zaza decides to embrace Marion's teachings and decided that, actually, SHE should be the one bullying Sophie leading to her continuing the cycle of abuse while magically dominating Sophie. 2 Zaza decides to quit her dream and by into what Sophie said at the start of the game. This would lead to her either attempting to get revenge on Marion and failing leading to Zaza and Sophie getting dominated or with Sophie getting a small army of people to come with her leading to her defeating Marion, but never being truly happy knowing that she'll never achieve her dream. 3 Zaza caves to the pressure of both sides and asks Genie to help her make a deal with Castyxo that would let her take the quick and easy way out, despite Genie warning her that deal-making itself is an art form that one needs to be careful with and not rush into or else there could be significant consequences while rubbing her bottom. This would foreshadow Zaza messing up the ritual and/or deal getting herself enslaved to Castyxo as an eternal whipping girl.
