So the good: I like the character models and each of them seems at least somewhat like they should be (Not really close but for a porn game not bad and passable) I like the animations during scenes that would usually be a still image gives a nice bit of life.
And the bad: Game is buggy (Auska mission had me replay it 3 times and now it's stuck with no way to progress and I refuse to use a mod or whatever just to get a basic part of the game to work) the story reveals its hand way to early (like everything is spelled out in the prologue early) could be workable for a porn game but still having a bit of mystery would spice things up and keep it interesting and hey there is a chance for more twists and turns later but it just doesn't really feel like it so there's no hook to keep you attached.
The above issues could be forgiven however, bugs can be fixed and the writing can be improved. What can't be forgiven is the worthless MC. I mean seriously what admirable qualities does he have? He's supposed to be a genius yet he needs other people to solve all of his problems. He can't even make a basic plan to clear the house for a day without Power coming in to save his ass. He's not physically capable, which sure checks out since he's supposed to be a nerd type but he doesn't use his intellect to make up for it. He has the charisma of a wet sock and I'm convinced the only reason he gets the girls is that they literally have no other option. He isn't brave and has the willpower of a wet noodle so we don't even get a Deku or Naruto situation. The only good thing you can say about him is that he is generally a nice guy who wants to do good but he is so pathetic in every category there is no reason to believe he can actually get anything done. If you were to put 1 other guy into the story who was only average at everything he would still be 10 times better than the MC and he would be getting all the women.
I've said it before about other games but a worthless MC who isn't good at anything, who only gets things done because of sheer luck and plot armor, and who is a creepy pervert that is somehow a god at sex even though he has never been with a woman is not charming or exciting or quirky or fun, it's cringe. This MC doesn't even earn the title of mid, he is such a passive beta cuck that other betas laugh at him for it. And I'm not saying he has to be a chad alpha, he doesn't have to be OP with no flaws but at least give him SOMETHING other than a huge magic dick. Give us a reason to believe he is good at something that he can then build off and get better and better.
TL;DR Don't make the worthless side character your MC.
