Definitely an above average game with amazing atmosphere and art, but one that sadly fails as an H game for me. The main reason it falls short is that, despite the animations being smooth and nice to look at, they don't do that much. They feel mostly empty or weightless, but the primary drawback for me is that there's no "finishing" sequence for any of them. There's a slight change in the animation speed and gyration to signal that it happened, but that's it. No leakage, no enjoyable filling. They're nice to look at, but don't really bring it home.
The atmosphere reminds me a lot of other non H indie titles that find a lot of success, and it sets a really nice atmosphere for the enemies that you face. The gameplay is very basic, but the controls are fair enough that it wasn't awful to play through at least 4 ish levels.
The game has strange secret areas that lead to a...very ill fitting hub with entirely different music that shatters the mood pretty heavily. Each time you find the room, you get a scene with a bit of plot and a single CG. I found two, but neither were actually anything X rated.
All in all, an okay experience, but one that lacks the extra flare that I think is needed to actually want to play a game like this. I really don't mind playing it, but I just don't feel the gameplay is conducive to the H content I'm after, nor does the H content itself hold up with the far slower and exceptionally non-lewd gameplay. The animations are smooth, but basic.
A fine game, but one that is, in a word, lacking.
