TLDR: The two side stories are ok, but the main one ... Take a low quality linear visual novel with inconsistent story, add ton of farm and bugs, lock the content behind random gameovers (with no sex, it's just a text telling you to restart) and you have crucial investigation.
Now a bit longer, I won't talk about the two side stories that are pure visual novels and look nice with much more efforts put in, but are not really my cup of tea and not the reason I played ... Damn it ...
Now for the main story, it should be a visual novel too, but is in fact a lot worst. A visual novel let's you enjoy a story seamlessly with only your choice mattering on what would happen, here forget about that. First the story is hell of shitty, nothing makes sense at all, sometime your character obeys orders that weren't given to her, sometime she answers when nobody was speaking to her it feels like part of the script was cut down without any care, but well, you have a video to fap on, you won't read the text right?
Now let's talk about choices and mechanics, simply you would have none the game would be better. Let's talk about the start of the game, you are a cop sent undercover to investigate in a university with your boss planning to turn you into a whore (but you don't know yet). Ok sounds fun. Yet when you start the game you are in your boss office and are asked two choice, one is labelled "sex path" and the second nothing. If you choose sexpath your heroine will make a little tease ... Ok ... and earn 1 slut point. If you chose the other she behaves like a cop is supposed and you go on your day.
Now this looks almost natural in a porn game, the issue is, at this point you are already gameover if you chose not the sex patch, because at the end of the day you will have a check on your slut points and if you don't have 3, it's game over. The text is some random bullshit about telling you that you aren't efficient enough and voila. And that's the issue, you can do anything you want, you have to follow EXACTLY the path decided or you will have at best a gameover, at worst won't see any content and be locked in the same stupid loop forever with no content added.
In many games I enjoy game overs, I even collect them, but here there is absolutely no point, they are just punishing you for not following the linear walkthrough exactly. What's the point?
And the gameover mentioned above tells you, you did not made any progress in your investigation, in one day LOL. Really efficient police in the US. But don't worry, if you teased the first day and start to fuck anybody in school past day 3 you can stay there forever, no need to make progress anymore, no so efficient finally.
Now about the content, I read there is a lot of content (if you can access it) and that's true, the issue is it's quality. I'm pretty sure how the author add more content is simply browsing youporn he sees a video he fapped on, download it and stuff it inside with no care. Your character is blond with long hairs, don't worry she will swap to brunette half of the time, hairs going short to long, coupled with the bad writing and story that makes no sense, most of the time I'm wondering who is supposed to be the girl on the video that is displayed ...
No just no ... It's nice to make a game for free, but here I feel insulted. The only two nice things about this game is how some pics shifts when your stats rise and you become corrupted and the fact you can throw the game and keep the pics and vids for local fapping if you wish. All the rest is for trash.
That's too bad cause I remember playing it a long time ago, when it wasn't yet version 1.xx and it was pretty promising and it looked like choice had more consequences back then. Might be my memories not being accurate or i was more forgiving cause in development, but it really feels like one fo those games getting worst with each update.
