The good: NTRMAN's animations and art are top notch. Ever since Camp with mom 1, the games have been receiving the same amount of technical love, voice acting included. The uncle side was seriously enjoyable.
The disappointing:
Preface: I don't want to say "bad" because I seriously love NTRMAN and think he has the potential to create something truly special, he seems like a great guy (encouraging pausing Patreon subscriptions if he doesn't plan to release anything for the month and regularly updating us on Discord about his progress).
Unfortunately, this game was super rushed. If you want a perfect example of a "short, but sweet" title of his, Camp with mom 1 is the perfect example. For that game, it's at least somewhat believable why the mom would turn to Kengo given her lack of sexual activity. On the other hand, this game just jumps straight into the cheating for no real reason other than "the dude has a better dick". For the cuckold side of the story, she literally falls in love with the random guy after one fuck. On the other side with the uncle, although it is a lot better than the cuckold side, we never get an explanation as to how it got to that point. There's no build up.
I would have loved to see him just skip the, in my opinion, tacked on cuckold portion of the game, and just focus on the uncle. It didn't have to be long, at least 3 scenes explaining how she fell for him. In my opinion, his earlier works did this a lot better.
In summary, if you're looking for a good wank, the game provides that with top notch visuals and voice work, but if you're looking for something groundbreaking, this isn't it. I love NTRMAN, I've played all his games and I seriously think that he'll eventually create something game changing, but this isn't it. I hope he goes back to taking his time on his future titles (like the time he put into games like Adelaide and Mother's Lesson).
PS: I saw some commenters fighting about their opinions of the game. Look, everyone is entitled to their own opinion on this site (this review system is a testament to that fact), let's not attack one another because we have differing opinions. Is this a piracy site? For the most part, yes, but that doesn't mean we can't be critical about the games on here. That being said, let's at least treat these works seriously, NTRMAN and all other developers take their time to craft these games and the least we can do is treat them with respect. This can be expressed however way you feel is enough. Leaving reviews, discussing in the comments, whatever you want. Just keep an open mind and be friendly. We're all perverts in our own way, the least we can do is try to accept one another.
