I'm going to be honest, I don't know why I like this studio's games so much, it's probably because of the premise and because I like the artistic style, but in the rest of the aspects they don't come out very favored.
They are roguelike puzzle games in which you have to collect objects and organize yourself in the most efficient way to capture the adventurers (the mechanics are the same although in this one you "rescue" them).
About gameplay: The problem is that although it is entertaining, there is a lot of farming, to somewhat ridiculous points and the progression is practically zero, and I am referring to the progression in the porn content, gameplay yes there is improvement, although it is slow, and its slowness is probably due because there are multiple types of coins for multiple improvements of all kinds, to the point where you even have to improve the number of floors you can visit per exploration (causing the duration to be artificially lengthened, since progression is blocked directly ).
Mentioning that it is the first game you play from the studio can be somewhat confusing and overwhelming the number of items there are, the way to use them through menus and the way in which the improvements are distributed in the base (adding the factor of having 3/ 4 different currencies for upgrades - although only gold and mana are used in the dungeon).
Focusing on the +18 content, well that's fine, there is variation, there are always multiple girls in this studio's games that are captured and raped by a decent variety of enemies, and the style is nice, although there are no animations. The problem is that the traps/enemies that will generate your desired H scenes appear from the beginning, luckily, so there is no progression in this aspect, what's more, I wouldn't even say that it depends on the RNG, simply from the beginning you can find everything in the dungeon. the H content, since there are adventurers who have been defeated and when interacting the "scene" is played. This is not a negative thing per se, but since the game DOES have a playable progression and on top of that it is slow, let's say that hentai falls behind.
In other games from the studio there was some "farm management", you could put captured adventurers in traps or farms with monsters and they generated resources and you could see how they were abused, but this ended up translating into an even slower progression system because Leveling up those traps was normally hellish and although in concept it was cool, in this game there is something similar and it works as a gallery perfectly.
Conclusion: I would say that this is the best game I have tried from the studio, I think the systems are better explained, there is more variety of H content, some "mechanics" have been eliminated or replaced (like the farms that are no longer there, but for example now you can level up the girls) and in general there is an improvement (which is not always the case with the studio's games xd). The problem is that I think it's still not worth getting to the end of the game (although in several of these games there isn't even an end itself).
You can try it, try to get the H scenes and see if you like the gameplay a bit, it seems to me that the playable loop is decent, although it is not worth getting into it if you only want porn, in fact it is counterproductive.
