This game has a good and well-tested premise: Guy needs to rescue the city / country / world and build up a harem not only while doing it, but as a tool to archive his heroic deeds. Also, the atmosphere and and tone of the game are not a surprise: It is humorous, often breaks the fourth wall and doesn't take itself too seriously, while also trying to touch some more sensitive topics.
That being said, this also means that the game can be compared to others in a very direct way. It doesn't want to be original, it wants instead to give you more of the same and tell an original story within this frame. Nice, not everything has to be a great piece of art and not everyone should try to redefine a genre. But now the question: Should you play this game?
And the answer is sadly: Not if you have better alternatives. And that is not because the developer is bad or the story is bad, it is because of two very simply points:
1. The premise of the story does not work in the slightest.
Some might not care. I get it, it's a porn game, and most porn doesn't need to be very good in the plot-department. But since there are so many of these games, I can simply say: There are some that have a good premise, and some that haven't. This one has not.
Why? Because this game chooses an epic battle between Love on one side and Lust on the other side as setting. This war explains everything in the story and gets referenced a lot. The Goddess of Love is the good one, the evil Champion of Lust that controls people through their desires is on the other side. You must be good, win the heart of people over and not succumb to your desires.
So far, so good. Now: What if I tell you that every girl in this game is as horny as just humanly possible? Including the goddess of love and her followers (especially those). It does simply not work, not in the slightest. There is a difference between the story not taking itself seriously and a player that can't take the story seriously.
2. The game wants you to earn things. But there is no reason for it.
Conquer the hearts of the girls - yes, good thing. Works. Proven and often used by many developers and writers. Now, there is one thing you need for something to be conquered: Resistance in any way, shape or form. To conquer something, you must overcome obstacles.
This game doesn't let you have sex with girls, because... that's the rule. You need Trust and Hearts and all that. But... why? All the girls tell you while you first meet them that they want you, need you, desire you. But... then, you just talk and earn their trust and all that. While they repeatedly say that they want sex. So... the game wants you to talk to girls around 50 times, always about how great you are and how much they want you, just to get the thing that is always the topic to begin with.
And that doesn't work for anyone that doesn't skip all the text. It's just nonsensical. Because as a player, you do not feel great and wonderful. You feel disconnected from the story, because... what is even happening?
Well, what's happening is: You fight against some sort of "demonic" Archnemesis that wants to use the lust of people to control them, and while you are doing that, every single person around you is lusting for you and tells you that unasked every two minutes. And your protagonist wanders around and does things. Not very many things. Just... things.
And the worst part is: There is some good writing in here! Funny jokes, good quips, some nicely thought out scenarios, a good variety of different characters that behave differently, have their own motivations and backstories... sadly, they can't use them because they are more often than not just horny shells, but it's all there! It could be a quality game, it has what it needs to succeed, left unused and neglected in some corner.
I might be in the minority with that opinion. But I never before wrote a review because there is this stark contrast between the good work of the developer on one hand and the overshadowing need of the game to please the player at every step of the way. Always tell the protagonist how sexy he is. Always tell him he is wanted. Always be horny and available.
I hope that the developer, at some point of the way, trusts himself or herself more and risks to make the player work for what he wants. Not in the form of senseless grinding, but within the story. Let the girls not like him. Let him conquer. Let him fight for affection. Other games handle this better. Many others worse, but the talent is here to do something that can be compared to the best this webside has to offer.
