Really, a nice game, actually. First of all, I know what is your greatest fear going into playing a non-Ren'py VN - crappy interface - but it's not the case. This game has a really nice interface with skip, log, and a convenient save system - almost equivalent to Ren'py.
Now the story. The first thing that I liked is that the characters are not complete morons. The characters are quite believable and have some depth. The story also does well to keep things interesting so it doesn't feel boring. The dialogues are also more or less realistic - they talk in a way you expect adults with fully developed brains to talk. The sexual events are formulated well enough that you can digest them.
I have one complaint though - you see the cute nerd girl on the cover of the game - Ann ? I gave this game a shot just because of her. And in the beginning, I liked her type. I was thinking, yeah, smart and pure girls like Ann are worth 100 Vannessa's (her slutty friend and your friends GF). It made sense since she seemed to be the "focal" girl of this game. But unfortunately, I saw little character buildup (other than sexual progress) on her part compared to Vanessa, who turned out to be a much more interesting character compared to Ann who seemed quite bland. As a self-proclaimed nerd myself (just kidding, I don't need to proclaim it really
), I find that quite offensive.
I hope there is more depth to her character that would be revealed in the coming updates, otherwise, I would assume that the writer doesn't know how to write her type. I'm only saying this because he/she wrote Vanessa's character quite well.
Overall, it's a really good game. It's got good replayability with quite a few different branches. It has good attention to detail and maintains quality. I didn't have to think twice to give it a 5/5.
