V2.20
In a word, boring.
As many have said, this could be compared to that one pocket monster catching game in the sense that you more or less capture girls to add to your roster of fighters. That being said, the following would be more apt.
It's like Pokemon if the game was slower, had a horrible UI, significantly slower and poorly balanced fights, and a dash of hentai.
You will spend the vast majority of your game running from point A to B while fighting enemies in the slowest RPGM combat I've seen in any game with art quality like this, and though it has the usually praise worthy addition of an "auto" fight function...even that requires you to button mash to get through each popup box that accompanies any attack. The combat speed as a whole goes at a snail's pace, and that's made all the worse by how boring the fights are. Your characters deal very little damage, the enemies deal drastically more damage, and you are forced to sit here spamming heals, damage, and at times, the capture spell in the hopes of capturing the single zone specific girl before they use a spell that kills themselves.
The 3D element is a very nice touch for this game, and although I didn't first see much of why it existed, I immediately was fond once I entered a spiraling stone stairway. It added a very unique feel to the 2D on 3D feel, and the look grew on me. That being said, the map design is atrocious, being akin to scribbles on a map in an attempt to make you run around collecting what few items are scattered about while you slowly fight through enemies. Though there is an item that reduces the rate that enemies spawn for a limited time, you'll still fight 5-6 groups of enemies before you get from one end of it to another. The item exists, but it sure doesn't do much.
The art within the game is made by several different artists, meaning the quality is often a mixed bag. Some characters look far, far worse than others, where as some look incredible.
As for fetishes, the spread is...odd. Sadly, it seems that it's primarily tailored very specifically towards people into breast feeding, as over half of the base game's early game content is just that. Breast feeding in most cases, and breast feeding with a handjob in a few. Within the first full hour of playing, I had only two scenes that didn't revolve entirely around breasts, one scene of which still started with breast feeding. The other was vore.
The crux of this game's flaws stems from its horribly slow progression and combat, all of which is made worse by the shockingly sparse hentai. This game seems to be far more focused on having the player fight an uphill battle for every scene they get, and despite how many scenes it looks like this game has within it from the preview images and 3gb size...you sure don't get much out of an hour of gameplay. I've currently unlocked no repayable scenes that don't game over me. To get scenes with the girls I have, I need to rank up their affection with me, but so far I've only managed to rank up their trust.
As I said before, this game is just dreadfully boring. The writing is...pretty standard for hentai, and the quality of it rarely influences my feelings on the game. The most off putting thing is not the potentially strange and even unwanted fetishes, but the fact that after a bit over an hour, I've only been met with as many scenes as I have fingers on either hand. Having genetically normal hands, this number of scenes would be better if all were full scenes, but they aren't. Several I found were just brief stills, a few sentences, and then the screen goes black and you hear your character getting milked...you don't even see anything. A lot of what happens is just implied, and I really don't feel that the excessive, excruciating grind is worth an implication of lewd activity.
If you have a LOT of free time and don't mind a GUI straight out of 2002, you can probably stomach this game. If you enjoy breast feeding above most other things, you'll probably really enjoy this game's start. If you want...anything else, you're in for quite the wait.
