Well... this game was thoroughly mediocre... then again, I suppose that's par the course for this circle. They've never released anything particularly good.
Ok time waster, great art if you're into this particular art-style, and decent scenes for what they're worth...
However, the story is utter meh and the "big reveal" is unsubtly spoiled by the game's title and description to the point where you can predict almost everything before you even play the game. About the only surprise was that one sloot's origin and nature... but that's really not much.
The gameplay is completely uninteresting with no attempt made to make it interesting. It's so tacked on that the dev even gives you the option to bypass 90% of it via instant monster-kills. Now, that's not necessarily a bad thing... if the boss fights were at least interesting... but they're absolutely not.
The worst thing, however, is the flow of the H-scenes. You can unlock something like 80% of them very fast through normal gameplay, and then the only thing that's left is a crappy story and a trickle of H as you rush to finish the game. On top of that, the H-stats aren't really made to work well together. The nature of the H-scenes is dictated by the heroine's lewdness stat which increases from absolutely anything lewd. So while the H-stat screen might say that "eww taking it up the ass is weird" or whatever, she'll totally lose her mind and be all over that D when an anal sex scene happens. So that screen is very poorly done.
Honestly, peeps that just unlock the gallery and watch the scenes don't lose out on much except a bit of context for a few of the scenes... like... 2-3 of them or so...
