While some aspects of this game are good, it is also plagued with a few problems that detracted from my enjoyement of the game.
I'd probably put this game as a "3.5 stars" if I had the option to.
____________
The core gameplay loop here involves playing as Isalia who is undercover as a prostitute in Rudil, where you must find clues about the Black Spider gang operating in the area and stop whatever plans they are preparing. As with any corruption game, you can involve yourself in the various sexual harassment events and Isalia will become more corrupt and open herself up to prostitution and other such events as you play the game.
The events themselves are pretty good and there's a quite a range of them. There's some sexual harassment events, some where Isalia prostitutes herself and a small amount of enemy rape scenes in the 3 dungeons the game has. Most of the events are based on Isalia selling herself out though, but there are some unique ones such as the Esthetic shop or the mage giving you a special drug.
I quite like how the scenes change based on the debauchery level, as almost all of them have various changes in how Isalia acts and reacts to the encounter. For example, when she is groped by an old man she will go from outright to disgust to slightly enjoying it and then being very turned on by it. I suppose this is pretty standard for a corruption game, but I liked how they did it here. She also has a pretty good "disgusted" face in some of the scenes which personally appealing to me.
However, I want to focus a bit more on the issues I encountered since this game has a lot of praise already.
____________
The main issue I had was how the combat of the game is not really well integrated with the core gameplay. When you finish the opening, you get the choice to explore the 3 dungeons the game has by leaving Rudil. However, the entire story of the game takes place within Rudil and the only possible reason to do this is either if you want to earn money outside of prostitution (which is incredibly inefficient) or if you want to level up to ensure you can beat the mandatory story fights the game throws at you.
While the story does make you earn money at various points, you can just earn this via the various events around Rudil so combat is in a weird place where it just suddenly hits you through the story with mandatory fights.
None of the quests require you to enter the dungeons and level up, so to me it ended up feeling pretty seperated from the rest of the game.
What this causes is a problem where unless you are going out of your way to kill enemies in the dungeons, you will struggle when the game forces you to do the combat in the mandatory story fights. The Southern Cave is fairly easy, but if you try and go to the other two dungeons then suddenly the enemies are very difficult and you will need to level up a few times and use SP to get some skills. The ATK Reduction skill was particularly handy for me, as some enemies end up doing 200 damage every hit and you don't have that much health to begin with.
I also attempted the arena, but it felt like I needed to be a much higher level to handle the B tier and A tier fights so I didn't actively grind to gain levels and only fought when it was convienient. (The hunting minigame was fun though)
____________
At least in my playthrough, the combat encounters didn't really flow together with the difficulty versus how you level up and I felt like the southern cave was too easy but the forest and the mines were too difficult.
I had to rely on using a ton of MP restores to get through some of the fights, and the final boss fight in particular was a tough endurance battle as I constantly debuffed the boss with ATK reduction and used a lot of potions.
I felt severely underlevelled for the boss, which shouldn't really happen since I did explore all of the dungeons available as best I could. It might have been easier if I had bought the higher tier weapons, but I needed the money for some of the H events, and I didn't want to just spam the brothel over and over 20+ times to get the money needed.
____________
The money problem also extends into the events. The Host Club requires 4000 gold every time you want to do it, and you need to do it a lot to progress the event.
If you want to go the NTR route and have Isalia break up with her bodyfriend, then you are probably going to spend over 20k gold just repeating the host event. This also leads to acessing the underground brothel which is quite tricky tbh. It was far faster to get 100 debauchery than it was to finish the full host events.
You also need 15k for the micro-bikini which just lets you access 1 event with a micro-bikini enjoyer, and 10k for the story. Doing this through combat is very difficult since you only get around ~2000 for defeating a major boss of the dungeons and regular enemies don't drop much gold. Including buying a sword to do better in combat, there was a lot of things requiring gold and getting that gold would require spamming events over and over. For me at least, this was not balanced well.
____________
I'll also mention I had 2 instances of the H events not really flowing well. One instance was that you can go into the Inn and have sex with a dude at 40 debauchery, which is sooner than when Isalia decides to lift the ban on full sex. It felt slightly out of place since I assumed that beyond 50 is when she would be fully comfortable with having sex with people.
Another instance was that after I had just done the Brothel event and raised the cap beyond 50, I went into the male side of the hot springs and encountered an event where Isalia was extremely into being seen and felt more like a scene you would see at 80+ debauchery. For someone who had just lifted the ban on sex, it felt out of place.
This is a more minor issue though as they did put a lot of effort into the scene variations based on debauchery level and this problem happens in most corruption games that let you freely do events in whatever order you want as long as you meet the lewd level rquirements.
____________
Overall though the game is still fun if you focus on the event side of things, and I like the art and corruption the game has. I can see why people like this game as a one on the shorter side of things, but the issues I encountered were annoying enough that I can't really give this game a four star score.
