Yes, I'm going to say it right here and now... this is a kusoge.  Oh, there are some good points...but unfortunately, the really half-assed way things are done between and after the most vital points kind of make this VN the crap it is.

First, this VN as a whole suffers from the 'didn't go far enough' and 'not enough detail' syndromes.  Even the romantic elements in this VN feel truncated, and that is usually the only story element in which charage excel.  Why do I say 'didn't go far enough'?  It is fairly simple... the combat scenes in this VN are mediocre, at best, with a feeling of 'uh, is this supposed to be interesting?' that is worsened by the poorly-calculated use of moe elements.  There are some good CGs in this VN, but the way they are used is... uninteresting.  As for lack of details... there is literally no real detail to the endings, the conclusion of each of the heroine stories is so quick that you have to ask yourself 'eh, was there drama here?' 

I was outright amazed by the way they managed to completely waste the setting.  The protagonist is a genius... so what?  They never really use that element outside of the endless tests, and he doesn't really show it in the battles (the battles are so simple that they make the protagonist actually seem like an idiot).  I kept getting broken out of the characters' world view because of that.  There is no sense of style to the scenario design of this VN whatsoever, and I was absolutely amazed at the failure of the writers to actually make such an interesting setting work.  It is like someone handed a one-handed monkey a ten thousand dollar set of paints and a hand-crafted artist's brush and let him go on it.  This VN started out with promise and crash-landed completely.  Sorry to say, but what little joy I got out of this VN is ruined by being buried in the crap that enveloped the rest of the VN.
