I just finished the game recently and I can say this is one of the best I ever played. Taking the first place together with Dengeki Striker. Hehe
I enjoyed all girls good ending, every one of them had a diferent yet great story and a nice ending. I am a vanilla guy who always love the "happy ending". I liked how Haru story end, yet with all the bad things she and Azai had to fight, I had mixed feelings.
Still this was a great game. Hope I can find another similar like this game soon. I think the next one I will try is Kira Kira.
