ohhhhhhh. Forum Necromancy! I think the people who are interested in this game have already figured out what to do.
I have read the guide before and I can never get the Harem 2 ending he talks about.
Anyway since someone has already committed grave-digging (I prefer calling it that instead Forum Necromancy) and therefore I don't have to I will talk about my impression of the game. I don't really consider the part I marked spoiler to be an actual spoiler but I just but it in so I don't piss off the people who want to know
nothing about the story before they play it.
This game is one of the better games I have played. I did like the 'OMG were have gone into a parallel world' thing. I felt that the scenes were written decently. The characters, well, they did have some depth although that is not saying much when talking about the shallow pool that Hentai characters spawn from. Its just established that the blue haired one is the shy, submissive seamstress. The red haired one is the proper, pervert hating girl. The blond the loud, happy and overall annoying girl. The purple haired teacher..... I don't know much about her. They only talk about her near the end of the game and I was skipping at that point. The art? Well I am not a good critic of art but I guess it's good. The story, well the stories good. Apart from the usual cliches such as the non-existent parents (I would have liked to seen them :P ).The only things that disappoint me are: No rape scene were the annoying blond gets her comeuppance or
an option to join your brother and take a girl to the dark side of sex. :P
