Start this on easy. That's my advice. Its no fun to have to hit an enemy thrice - 4 -15 times as much because hard mode made him too damn butch.
Do that and you have a (mostly, fuck the third floor and its 15 enemies summoning 15 more enemies fights) balanced RPG with really poorly thought out progression, wherein the fastest way to get strong is to simply never finish any floors and repeatedly rest until you buy all the good shit, because you can't lose a floor until you first take it over - apparently the entire floor being in disaray under a big bad boss man is a lesser deal than literally 4 groups of 2 dudes wondering in circles.
The goal is to pass edicts which costs points and goal gained daily to get stronger, unlock new minigames, etc. But passing days has a chance of making 'conquered' areas rebel, which lowers 'control', which lowest another value I forget the name of each day if its < 0. So just keep control over 0 or never actually conquer and you have infinite days to pass for infinite money and edicts.
Now if the core gameplay loop is so fucked the best way to play is to essentially not play, and the balance goes to shit later, even on EASY, why am I rating it so high?
Its because its hot. Very hot. You start with your arrogant cow titted warden stomping weaklings, then she gets groped one too many times and starts liking it. So they grope her more. And she likes it more. Until eventually you unlock the ability to tit fuck men into submission. You collect passives doing this, which stack, making you gain x lust (ie tit lust, how much you want your tits groped) per turn or start with it higher.
Then you add the loss rooms (first floor is a blowbang, second they try to fuck you, third is for tit fucks) and minigames (being groped/fucked a secretary, drinking cum out of a mug) which also have their own passives and make it easier to spam the action you want.
Its just a really fun, gradual system, although it can feel TOO slow-paced at first.
The combat itself is, when an enemy that took 2k damage doesn't suddenly take literally 7 for no identifiable reason, decently fun. Because it ties into all the above. Enemies will just grope you if you get too horny (they don't rape, really, they specifically only grope Karyn when she wants them to), which they can tell better if you buy the right edicts.
But a lot of the time enemies will just take no damage from anything or your baseline lust becomes so high that you have to tediously spam 'lower butt lust' every fucking turn so they stop fingering her ass if you aren't into that.
Could really use chastity items or a way to lower lust at the start of fight beyond editing the save to remove passives.
To summarize;
If you want a balanced game, pass.
If you want to jack off quick, pass.
If you want a slow descent into sluttiness with the ability to choose specifically what Karyn gets off to (ie my karyn is a virgin even at the end-game, because the game gives some bonus for that), then play it. Its one of the better corruption games around and especially if you want the girl to ENJOY it, genuinely, not just be raped until he 'mind breaks'.
