What was at first looked like a great idea turned out to be a load of crap.
The game has 5 episodes and must say only the first two of them were somewhat decent, then the shit started.
Considering how small the game is and tied into the various decisions made, it's simply unforgivable not to polish them to a high shine. For example, in episode 3 I found out that the game didn't give a shit that I didn't kiss the antagonist and they just stated it as fact that happened. In episode 4 they left the player no choice at all and forced the heroine to give a blowjob. Honestly, based on the first few episodes I really thought that I had finally stumbled upon a game where the depravity happens because of the player's actions and mistakes, but no, it's done as crappy as possible.
Especially noteworthy are the level dialogues and the logic of the characters. Here is one example. An incubus locked a girl and her boyfriend against their will in a church dungeon and forced them to play a perverted game. Meanwhile, the girl is also a war veteran and clearly must realize what demons are capable of. In the third episode he tells us to talk to the doll, the doll sends us to another room where she is about to be attacked by a living armor, the girl is terrified of this(!) (she is a war veteran, I remind you) but incubus appears and destroys the armor. The girl feels grateful to him(!) and decides to thank him, and he tells her that he loves her and that he's really a nice guy who cares about her. And then he says that he used up a lot of mana and his regeneration is too low, that why the girl should help him replenish his mana by giving him a blowjob! What kind of retard he thinks this girl is? And for whom such situations with this logic designed for? Fortunately, we can reject this pathetic attempt at seduction by a good-for-nothing incubus, but in the next episode we are not given a choice at all. This is the level of dialogue logic in this game. You know, if I was interested in playing these games just for the artwork, I'd rather just watch animations on a site like rule 34, and would leave it to someone else to enjoy a game with dialogues on the level of the plumber came to the girl's house to "clean the pipes." By the way, the same incubus is not able to basically push the right buttons on a girl to seduce her in any way, apparently realising this, he basically uses demonic magic to charm her. That's why I hate mind control games, basically any kid can make a game like that, you don't have to think about anything, just make the characters fuck because it's magic. And that's the recipe for success, you don't have to think about characters personalities, their inner conflicts, their personality traits when you can skip all that and seduce them with magic. By the way, the succubus manages to seduce a guy just because he is a typical virgin who forgets about his beloved at the moment he sees naked tits. So no real intrigue here either. It's also worth noting that up until episode 4 we are still given the option of resisting their magic, and preventing corruption. But it's just a dialogue option, which again seems like a laziness and inability to come up with original solutions. There could have been mini-games where we as a player would have to perform some sort of in-game actions to avoid being seduced.
All in all, initially I wanted to give it two stars, at least for the idea of a couple being corrupted separately and for trying to tie gameplay to corruption, but after reaching the 4th episode and realizing how unoriginal everything is done, I realized that it's a complete failure, so only 1 star. The art is also unremarkable, by the way. Sometimes I really wonder how some Japanese studios manage to make genitalia look normal, even with censorship, so that it doesn't ruin the scene, while others make it as shitty as possible. This game is the latter case.
