This game is hard to rate. There are parts I really like in equal opposition to the parts I loathe. The good and bad bounce off and dance with each other which keeps the game from being as great as it could be.
The foundation of the game is three main fetishes: Exhbitionism, Domination, and Humiliation. Most of the content is somewhere on the venn diagram of these three topics. As the description says, you play a prudish, strict teacher at a local high school, who is plunged into a whole slew of fantasy elements. She finds out there's an alternate dimension straight out of fantasy fiction, that she's actually a succubus, whom must engage in sexual activity or go insane.
So the majority of the gameplay is about juggling a few stats: You have two major condition states, Lust and Sanity. If the former gets too high and/or the latter too low, it's game over. Engaging in sexual acts slakes lust and raises sanity. Depending on the ratio of each, access is granted to new events and variations on scenes. You also have three "succubus contracts" you can opt in, each aligning with one of the aforementioned fetishes. These contracts open up content and grant abilities, but demand certain actions be taken daily during the game's time states (a common smut game mechanic), with failure to do so incurring greater penalties to your Lust/Sanity meters. Items exist to manage your Lust/Sanity, and money can be gained through doing typical RPG battles in the fantasy world or by following your career as a teacher, managing various school clubs, which reveals more content to follow.
Overall, it's a fairly elegant concept that doesn't strain the limits of what RPGMaker can do. I have to give it props on its design philosophy.
HOWEVER.
The flaws are just as big as the strengths. Chief among them are pacing, focus, signposting and tutorialization. The common complaint people have is being unable to figure out the Lust/Sanity management, which is the most fundamental gameplay mechanic. The game just throws you into sandbox mode and expects you out core gameplay functions. This isn't Dark Souls, a tiny bit of handholding isn't a sin for a porn game. This lack of conveyance informs every bit of this game's design. You'll find yourself in a death spiral and getting game overs because your options aren't made clear to you.
If you're lucky you'll stumble on a few options that should have been more explicit from the start. Chances are you'll have to resort to a guide, though. As a rule, it's a whole star off from me if I gotta consult an external guide for basic gameplay.
The problem is fundamental: those players that manage to avoid the death spiral of the Lust/Sanity mechanics end up in a recursive loop, because experimentation and exploration is disencentivized. The content doesn't signpost itself or emerge through intuitive play, so again, you'll probably end up consulting a guide. That, or open up an entirely secondary instance of the game, as I did, within the Recollection Room in order to keep the game's only tip system handy, because said room is only accessible from one single location. Even having an item in the menu that let you visit the RR at any time would have been a major step up.
Honestly a simple tracker that explicitly signposts the next step in the various paths, prokking after a certain number of days would have solved most of these issues. Players are naturally pushed into maintaining the equilibrium of Lust/Sanity to avoid game overs,, and that should be rewarded. That's what the game wants you to do, but it also wants you to figure out progress on dozens of content clusters through granular experimentation. What the end result you get is abysmal pacing, repeating scenes dozens of times because you didn't meet some obfuscated criteria, like wardrobe choice or a specific Lust or Sanity ratio.
On top of that, the game lacks true focus by featuring almost completely divorced dual modes of play. On one hand, you have a critical story path in the fantasy realm with a conspiracy and narrative. It's very linear. The sandbox mode, on the other hand, is all over the place. The two barely gel, and feel like they should have been separate, but related games. The focus on linearity within the rather tame fantasy story should have been directed instead to a through-line of the sandbox mode that naturally linked up the various plotlines, or the sandbox should have been integrated into the fantasy world.
As for the aesthetic, it's pretty decent, the renders are plentiful but basic.
I really spent a lot of time with this game, as the adult content really appeals to me. But I wish it was better designed. It felt exhausting to play.
