It's nice, I feel a huge hentai-manga vibe.
No, in fact I like that it is done in DAZ. Much more realistic. Far, far from hentai/manga - except for the story.
And, to be honest, there are 50 hentai-based games for each dozen in here. You do those storylines if you cannot actually create a story - much like a B/C movie.
What many developers don't get is that you start by setting up the world of the game. This is best done by actually writing a manuscript or even a short story. Then, you build it up and add to it.
That way, you don't end up with a lot of loose ends or mistakes that could be easily avoided by just spending a bit more time in preparation. An immersive game is not made by rendering 20 images (ok, 214 in this case) in DAZ or re-using a pre-made animation or two and then releasing it.
ALSO: The changelog??? Really?
ALSO-ALSO: The initial warning when loading the game. Yes, 18 years of age or 21 in some states. But ... ehm, the developer is not from the US, so he wouldn't need to consider this.
ALSO-THIRD: She is not a nurse in "chapter 2" which is in fact not a new chapter. It is just a continuation of the same male-female poses that can be downloaded here and on other sites. There is no creativity in this, other than an uninteresting story about a prostitute.
The game has ONE quality. A gonzo-like story style (no, not hentai or manga, but gonzo) in which the player is the protagonist, but never seen, and he is talking to the game character thru dimensions. I liked that. It immerses you - but it is not enough to save this story, unless you are provided with choices and/or there is some kind of management. As a story, it fails in my opinion.
