I do really want to give this as a 5 as i really, really like it. It's just a shameless, generic fuckfest but some things bothered me too much that i have to lower it down.
As mentioned, the game overall is just a giant fuckfest. There's no more depth to it than that. Any sort of character or plot development relates to fucking. For a game that had its first version released in May 2020 and its final version released in December 2020, there is an absurd amount of content for a finished six month game. Each scene is convenient to unlock and replay and there's an easy in game guide for each love interest that tells you what to do, where to go and at what time to progress their story. If you want a more ambitious, interesting, fleshed out story this game isn't for you.
Only thing that really bothered me during the first half of the game is how naive and sheltered the MC and Cathy come across. They're supposed to be 18+ but their sex education is worse than a 10 year olds. Can get annoying and a bit eye rolling, feels like the dev wanted a shota MC so wrote dialogue for a shota MC but he isn't actually a shota so the MC just feels like a dumb manchild. Didn't have a problem with anything else in the first half. Very convenient progression system, minimal grind. You spend time with a character to build up there SP which at the start of the game is only talking to them but its like a 5 second conversation lmao. As you unlock more scenes, you can replay certain scenes at certain times of the day to increase their points. Dunno why you would bother talking with them instead of just replaying your fav scenes.
Around halfway through the game, they introduce a magic system and goddamit that is the main reason this review isn't a 5. Fuck that magic system. It slows progression down a lot as you wait for each spell to recharge but there's nothing you can do to make it recharge quicker. So you don't want to replay scenes that need a spell as they'll lock you out of progressing a character's story as the spell needs to recharge, and certain events need the spell to be charged. Would really advise just accessing the console to increase each spells charge whenever you need it, really fucking annoying otherwise.
The ending is also crap, but meh as mentioned no one's playing this game for its story. Like the one plot point the game has is that you have to impregnate every woman in the house to save the world (even the succubus and the god). To reach the ending you have to impregnant 6 characters but only 2 of them show up in the ending. 1 of them just says "SEE YA", and the other 3 just disappear never to be seen again. So like... why push the point that the main character needs to impregnate everyone if you're only gonna bother including 2 of the characters?
The above are the only things that particularly bothered me tho. As mentioned, the sex is the focal point for most of the game and that's great. All the girls (asides from iBelle) has a good amount of scenes , and the scenes are really good. Good animations, good renders, good dialogue. Quite a lot of the scenes are First Person POV so while i quite like that, it may not be your thing. There can be some minor inconsistencies like the Elf character's rendered backgrounds during sex scenes just do not obey the laws of gravity, and there's a nitpicky personal issue with the redhead where you're fucking her cowgirl and it's POV so she's looking straight at the camera, but then the camera cuts off to the side but she's still looking straight at the camera which makes it look a bit awkward as the scene switches between those 2 angles. But that's nitpicky stuff, the sex is more than good enough to live with those inconsistencies.
