I wish I could give it 3.5 stars. I am leaning towards 4 stars to balance most other reviews that are rating it so low. This review is more of a rant than a review, and I apologize in advance for that.
I believe the review from AHentailurker bellow to be nearly perfect.
Now regarding most other reviewers, they frankly seem to me to be completely delusional.
You cannot tell me that the characters from Hunie Pop 1 were well fleshed out and well written. They were one dimensional stereotypes, and the most development we ever got out of them was when we first met them and learned the basics of who they were. Similarly, Hunie Pop 1 wasn't really a "porn" game. It was a game with sex in it. Lots of people are complaining how Hunie Pop 1 was more sexy or more engaging in general in terms of erotism, and, while I don't disagree, I think it's way too harsh to call this game worthless simply because of that.
Now, yes, I don't think people are wrong when they say characters from HP1 felt more... "real", so to speak, than the ones from HP2. This is likely due to the fact that in HP1 having sex with one of them was much more of an ordeal (in the good sense), with us getting progressively closer to them little by little. While in HP2 we have an omega chad who can just have threesomes at the drop of a hat. Yes, I agree, this is downgrade.
Regarding the erotic content, I also agree that not seeing the girls undress during the "fast connecting" thing is another downgrade, as are the CGs. Admittedly, I haven't seen all CGs for this game yet, but the ones I've seen feel very...lackluster, somehow. It feels as if the girls were deliberately posing for the scene, while in the first game it felt like the artists captured an spontaneous moment during/after the sex.
What bothers me the most from these reviews, however, is how people are bashing the puzzle system. Look, I don't know about you, but I sure as hell didn't want the 72nd reimplementation of vanilla CandyCrush. Stamina, baggage, separating sentiment and passion for the two girls, the ability to switch between them, all of these are additions that enhance the core basic gameplay, by forcing the player to actually use their fucking head, instead of just matching stuff at random. If you want a more relaxing experience, there is an easy mode. Once again, yes, the specific implementation of the baggage system is weird, as sometimes it completely changes the way you go about things (without affecting difficulty, or even making the game easier) and other times it just makes things harder in a somewhat artificial way.
The jokes are fine. Same brand of humour we had in HP1. I don't get what these people saying that it got worse are referring to. I like it.
All in all, it's an ok successor. It's not amazing by any means, and it baffles me how the developer took so long just to implement a handful of new mechanics. Like, he had most of the thing done, from HP1, no? Was it really that difficult just to program in stamina and the other stuff??
Final score: 3.5/5 - I NEED MORE KYU CG YOU MOTHERFU—
