It's a good game, better than 90% of VN (spy your landlady under a shower thing) but it has its flaws (I'm writing it after playing Chapter 4).
The story is not original and heavily inspired by Vampire The Masquerade lore but it's allright and well written although a bit slow sometimes.
The graphics are mostly good. I disliked small things like almost everybody having "pretty boy/girl face" (it's a common problem in VN) and passsing the same shop again and again while riding a car.
I would like more choices to be made in the game as most time you just click and skip dialogues. And when you actually make a choice you don't know how it may influence the story. People say here it may have impact several hours later, I have to believe I guess
Oh, and the sex scenes are very, very rare. There is a lot of nudity (pretty looking, I have to admit) but nothing comes out of it. And when you at last have sex, it's some totally unimportant random side character. So play it if you are more after the story and not erotic scenes.
I'm giving it 4 stars a bit in advance but the author made a lot of work and despite the flaws it's on the good side. Especially if you like vampire stories.
EDIT: Now the game is finished and has really a lot of content. I wanted to give an extra star for it as it doesn't happen that often and a lot of games get abandoned. But I can't.
Unfortunately towards the end the story gets worse. There is a lot of unnecessary talking and the ending is bland. The earlier chapters were better.
There are some sex scenes in the game but too few for a porn game and too much for an ordinary game. They would look okay 5 years ago but now are a bit outdated with old body models and no animation.
There are stats and skills but they are mostly "fake". The game is actually quite linear and no matter if you use some skill or not the final result will be the same, just a few in-between pictures will be different.
Still it's better than many other similar games. Maybe it just means that many games are simply poor?
