One of the three stories that I played was pleasant and mostly wholesome without any shaming or unexpected detours or kinks.
The other two stories are largely your run-of-the-mill stories about the MC's partner being encouraged to explore themselves. However, at points both mention the M.C. has smaller genitalia than the new partner. Whether or not the developer understands this as a kind of shaming, it's still its own kink and should be warned about... ESPECIALLY when it's not mentioned at all up until the moment of the partner either engaging in the act or recounting it. Even moreso, in my opinion, when the MC goes unnamed. It should be expected, intended or otherwise, that an unnamted character might serve as a self-insert for the reader/player to immerse themselves. It's a conscious choice by the developer(s) to be so pointed about comparing sizes. I would have preferred there be a warning for this kink.
I made a point of leaving feedback about this disappointment and how it ruined any desire I had to explore the other stories, and the dev asked me to give another character's story a try. Lo and behold, the exact same thing an incredibly similar thing (with a slightly different circumstance) occurred in that character's story where a viewer could be led to believe a very similar degradation has occurred for the MC. Frustrating, especially considering the time investment to reach that point. It leads me to believe the author is just trying to make a porn game. Fair enough, I guess.
The art isn't notable or special; nothing really sets it apart from all of the other AI slop in these games. There are a few animated portions which is always a pleasant surprise.
The characters are not memorable, nor do secondary or tertiary characters seem to exist as anything other than mechanisms to drive the plot forward. I found it hard to believe anyone 'existed' in these settings other than the MC and their LI.
I'd say I didn't notice many grammar or language issues, but to be honest I didn't notice any. Definitely a plus when so much content is barely readable due to horrible translation or completely busted or archaic idiosyncratic speech, with sentences that no human alive has ever spoken. Attempts at humorous conversation between characters felt at least a little less unnatural than many games, which I'd score as another plus.
There isn't a significant time investment to get through the content available. You can finish it all in a couple of hours if you're a slow reader.
TL;DR there isn't anything exceptional about this game in the landscape of AI NTR slop, and if you prefer to actively avoid the kink of size shaming degradation then this is one to miss. However, there is one wholesome and fun story to be explored for a bit of a smile and a break from goonergaming.
Edit: A response to this review made some less-than-generous assumptions about my state of mind and intelligence rather than acknowledging that some people have difference preferences and that's okay. I encountered content I both liked and did not like, expressed such and why, and was insulted for it. Perhaps this is my lesson learned: poor quality stains deeply, and searching for quality in AI slop NTR phone games is a fool's errand.
