Pros: 

Art style, animation is good!

Direct VN story type, Very low amount of sandbox itens.

Sound and effect very good: although some are memes and cool to have sound effects, like i hate those type of silent games, it make me rancid!

Cons:

Too much Femdom Content: Seriously, it´s way too much of that kind of content over here, honestly it´s 95% of the game in question!

Low amount of H Scenes:

More than 3 years of develompment and yet, this game have a decent walktrought, not to mention of the development time, its too long  between updates and the duration of game updadte is very short. "this game, only get 1 update every 10 months... so, one update per year!"

No gallery of scene replay.

There are lot plot holes.

Choices have little branching paths and cutscenes that affect other later on.

Long dialogs. quit heavy text for a VN.

Overall: I wish MC would act a little more like a man, not too pussy shit guy, MC always threatened like a shit every day and he didn´t even try to think about how to gain the upper hand or fight back! I hate these type of character, this dumb and silly tropes animes is overrused!

No to mention mixes with plot holes, since men have been eradicated by a disease, wouldn´t it be better, the MC to be treated like some kind of god than worthless sack of shit?

Rea is supposed to be the hero fo this VN but she acts like a shit villain, also she is quite annoying and the mc´s attitudes is uncooperative. all she does is say "I´m genius" and "Now, go make me some money" for fuck sakes what a  weird shit girl.

She is a genius who managed to go back in time to kidnap mc to make him a slave in the future, but she didn´t want to go back in time to prevent male humanity from being extinct. Holy shit, that´s what a i call supreme selfishness.

I don´t know what her thing is, but after that there no way i can stant a character like that. she is shit caracter, i´m not going talk about the communist girl or that little rich princess who rent the mc to rape the poor girl.

Anyways, too many negative to mention but keep in mind this supposed to be VN hentai lol.

Still, when a game is made especially for a certain niche community, the game lose half of potential. like its obvius what game was made especially for those who enjoy fetish Femdom. but what save this game is at least MC choose the path he want to follow, but his BETA TYPE personality is wanting to be desired.
