Hello again,
This time we'll talk about the erogè I most liked between all that I played till now. Its name is "Kitto, Sumiwataru Asairo Yori Mo" and is made by the company Propeller known for "Bullet brothers" and others action series.
Let's say it before I start so probably it would serve as a warning. Go and play immediately this game if you still haven't, this is in my honest opinion the best game (global-wise) from the last few years!!!
Story :
The story starts up quite simple. A boy, Suu Sasamaru , go to a art school in the mountains where he knows that will be reunited with its childhood friends, Kumigami Hiyo, Yumeno Araragi, Kashi Harutsuge. He is quite positive about the reunion, when he arrive instead all, but Hiyo give him cold shoulders without him knowing why this is happening. He has been told through mail by Hiyo that all were waiting for him to return...after some initial refusal he decide to pick up the situation and shows his own friendship to the others by becoming the leader of the effort toward the festival happening in the school where each class (identified by a color) fight the other class with an artistic concept following their own color.
This is a very little part of the true story. After the starting part where he tries to recover the lost friendship, things start to go weird. The whole game is divided into loops in which the story resets by unnatural means into determined part of the story, but take another branch. He fails to understand Hiyo feelings (in the first loop), and a sickness expand in the school in the others.
One thing I can say for sure. You won't be bored for most of the game, the game is filled with new content and never a filler space and everything will lead you to the UNIQUE ending of the game (yes this game has NO routes). You'll either explore a past event of either the main characters or some supporting character, or they'll make some joke or some obscure reference (I loved the talk between Hiyo and Suu, thought had to use wikipedia more than once to understand wtf they were talking about. 
)
Characters :
Each one of the characters are well defined and you can really touch their growth through the whole story. You feel their pain like they were yourself, and I admit to had cried once in a particular emotional scene.
Apart from the main four characters, we have a couple of recurring important characters. First of all the "blue sisters", their personality quite opposed and always seen together. (quite cute both), a delinquent from the black class (Nakarai Nobuo), the professor from their own class (Onitake-sensei), the misterious student council member (Waka) and some others. All of them have particular personality that get interwined with the others during the game. All of them have particular past or motives to their actions.
Sound :
This is another great part of this game. The OP and ED are very beautiful songs from White Lips and the entire sound track is literally fantastic (I heard it countless times).
The voiceover of the characters was quite realistic and (incredible to say) even the main character was voiced (and had a very good voice) thought I cannot say the voice overs are at Fortune Arterial level.
Interface :
Quite standard interface, but very well designed graphically. It's certainly a step up from Fortune Arterial one, but still nothing that stands out. They could have gived us some more goodies. 
H Scenes :
The H Scenes were few (three of them) and almost all focused on Hiyo, the true heroine, nevertheless were well done and pretty romantic. The CG used were graphically nice just like the rest of the game. Scenes are fortunately well timed, and with no sudden appearances.
Conclusions :
What are you doing still here? Go and PLAY IT. This is a game no sane person would miss (if they care even a little about the story).
