4/5, almost phenomenal, but held back by a long-term problem.
So, before I say anything, this is one of the first H-games I ever played (think back like 2019-2020), and for that reason, it has always been one I'm happy to see again. While I will be touching on what keeps it from being a 5/5, I will explain what there is good about it first, and there is a lot.
You play as a school counselor at a local university, and your specialty is hypnotism. Since this is an H-game, this isn't the boring, light suggestion hypnotism, but the kinky, slutification kind of hypnotism. Your character (either a man or futanari as you choose) can then go forward as you see fit, brainwashing students, teachers, or town locals into being your obedient sex toys.
The game is formatted interestingly, having a mostly text-based format between your character's internal thoughts, and the dialogue between characters. However, there are tons of pictures throughout, all made by H-artists, and showing all sorts of kinky things you do to them. Sometimes your character will be presented with choices, but most of these either progress the story in a linear way, lead to a game over that you can just reload a save from, lead to one of the game's many endings which also can be reloaded from easily, or just give you a list of scenes you can do in any order. There are in-game stats, but it pretty much just determines if you can access a scene, progress the story, or how much you get paid for the counseling job. No skill checks of any kind.
As for the H-content, it has it in loads, and tons of kinks, but they all circle back to your character being the dominant one (with one exception where you surrender to another hypnotist, but its a Bad End). This is everything from corrupting a family of women to be your sex slaves (and more than one family), you mind controlling a women's athletic team until they are all free-use for you, and ultimately, consolidating the entire school into your personal harem.
However, that's just half. If you are more into femboys/yaoi content, the other half of it pertains to your character making a pact with a male succubus (incubus?) and corrupting the young boys of the setting into femboy cumdumps for you. You don't corrupt the whole school in this storyline like you do with the women, but it has its own character's, scenes, stories, images, and endings separate from the straight content.
The best part is that upon booting up the game, you can toggle either of these modes. Prefer the straight content? Toggle Vegetarian Mode (no meat, get it?) and no male corruptible characters will appear. Prefer all femboys, toggle Carnivore Mode, and no women will appear. Maybe you're super damn bisexual, toggle neither and both kinds of characters will appear, and you can pick and choose which ones you go for. There are tons of endings, and if any character is not your cup of tea, you don't have to interact with them at all to get an ending.
Now, this game is short, so, you'll probably get many endings on just your first sitting, there's more than enough here to keep you entertained for a while.
Now that's a lot of praise, so, what is the downside? Simply put, the way new content is added. What is here is good, but many times now the devs have prioritized adding new characters and new storylines, often leaving previous ones unfinished. Many of these unfinished ones have been unfinished for years now. You will be following a character's story/corruption path, get a few scenes in, and then get the notification that you have reached the end of that character's content before there was any pay off, and many characters have been in this state for months or years, even after new characters have been introduced and even had their storylines and endings finished.
As someone who has played this game for a few years now, and has had some characters not done for years, this is a blemish on what could be a greatly well-rounded experience.
I do recommend the game, but with this one caveat. I hope the devs will see this, and understand that I do enjoy and have enjoyed this game, but there are some things that need finishing that have been left unfinished for sometime now that need attention.
