There is something in the game that got me. Maybe it's the best male friend, who is fun and is not there only for the "male presence" in the game; or maybe the girls who are diverse and interesting.
The fact that the game has some music is helping a lot : it gets you in the right mood to play the game. So big point for it.
The "twist" of episode 1 seems easy and predictable, but clichés exist because they work in fiction works so I accept it.
The only "negative" point I have, is that I have the feeling that the game forces me to choose a girl early. I do not mind to have a choice but it feels so soon in the game that i will have to play a lot of playthrough to see a majority of scenes, and i would have loved to have the "big" choice (if that's the one, i'm not sure, because i didn't play much after the end of ch3 for the moment) a bit later, to have more "scenes" before having to replay the game to see others.
Also, I accept the fact that there is no harem story, but I really hope that apart from the Robin/Kira relationship, there will be place for other expansions. Not that it's mandatory, but because I feel the story hinted at least one (Cece&Linda).
Finally I want to say that the Stephanie story was unexpected, and that mystery totally sold me the game : I was really curious before knowing, and knowing, I was under the feeling that the devs know how to tell a good story.
So yeah 5 stars even with the mishap. And seen the number of "average" games I played recently, it's refreshing.
