This review is going to be different from my other reviews, because I don't think it's meaningful to make a list of pros and cons, as this game is so extremely narrow in it's scope, that for the vast majority of players who aren't extremely into the premises of this game, it will just be a long laudry list of negatives.
So, the premise of the game is that a short, skinny, ugly, socially akward, wimpy and outcast, shy and stammering but kind of perverted, sexually obsessed and creepy dude with no real redeeming qualities apart from being nice in general, gets a harem of mainly good looking girls through magical means (one of witch is a fair deal taller than him). The same magic makes their breasts and hips grow and their breast lactate heavily. Also, the magic makes them super horny and gives them the ability to orgasm just from having their breasts manhandled. However, by harem, I don't mean women he has sex with. Because he doesn't. As of version ep. 1-8 Part 3, despite hours upon hours upon hours of gameplay, there are two titfuck scenes and one thighjob scene and that's it. There is however a lot of groping of tits and pressing of hips and asses and breasts together both intentional and, quite ludicrously, unintentional. And a ton of focus, both visually and verbally, on the expanding breasts and to some extent hips and asses. Also some focus on women being bigger than men, sometimes literal giants in fantasy and dream sequences. I guess that's what you're supposed to fap to and maybe the people who is really into this particular fetish can do that. I can't.
So, I can't really say anything about the above, if it is done in the right way for people who enjoy breast/ass/hips expansion, or not. But I can, however, judge general quality. And much of it is meh*. Some is good, some is bad, so had this game contained proper sex of a kind that I could go for, I'd give it an average rating. Which is what I will do here. But bear in mind, for someone who isn't in to the above mentioned, this is basically a big waste of time. For someone who is into it, the small amount of games who cater to that fetish might mean that this game is a godsend, even if meh in general quality.
* To be a bit more specific, the graphics, models, background and so on is of an older version of honey select. I like it and it's competently done, but it's nothing special. Story is silly and could have been done better (the way the magic is introduced feels like a rather low level effort from the dev), but it could also have been done worse. Characters are varied and while a tad exagerated, good. Dialogue is in general carried out well, but not great and a good deal of it is bland, banal and pointless. Some grammer and engrish mistakes here and there, but not too bad. There are some choices, but not very many and it's unclear to what extent they actually impact the story. There is *a lot* of mindreading going on, coupled with entire scenes where the MC isn't present, even some of people who have nothing to do with the story. Together with the lack of impactful choices, it further reduces the first person immersion and makes it feel like more of a (silly) story that the dev wants to tell.
