The art is quite nice. It does keep a fairly consistent portrayal of the character in various scenes. But the game is pretty much an uninspired shovelware that seems like it was made over a weekend or something.
In regards to the gameplay loop, I found it decent enough. I actually like the simple but fairly balanced approach to the combat and dungeon/equipment progression. It's not anything innovative, but it doesn't feel like a chore for the short game length.
I would rate it 3 stars for average, but there are a few issues that bring it down.
There are a bunch of mechanics aimed at preventing NTR. From my single playthrough, it seemed rather unlikely you could prevent ALL NTR progression, but you can definitely beat the game before the girls reach their final stage and "fall." But there is a fundamental dissonance in this whole concept. Why did they add all these mechanics to prevent NTR, but didn't make a single non-NTR scene or gameplay reward for doing so? I'm not someone who goes for pure runs in the first place, but even I found it pretty pointless.
Secondly, the game just doesn't have very many scenes. It's 3-4 progressing scenes per girl, and once they reach the final stage, their outfit changes and they get a new line when you talk to them in the preparation room. There is no difference in the ending (not that there is really an ending to begin with) even if all the girls got stolen.
In summary, it's a decent short game to waste a few hours. The scenes are rather short but can be decently hot. However, the game is rather unfulfilling and lacks a proper ending.
