If you are looking for an 'adult' novel, then you will probably be disappointed. A very well done story. An actual story with more realistic interactions that I expect from an AVN. But it's still fiction. I've only done one playthrough. I am curious to see what the other branches of the story are like.
It's like you know, that thing. Just sink back into the inky blackness and forget any of this happened.
I played Nadia first. The scenes are better in Nadia, with more advanced graphics. But the story and the puzzles hold up here. I think playing a later one, made me appreciate the story more. If you have played Nadia or Genesis, playing this title is a good intro to those stories. Not perfect, but fun.
