Finally found some time to write a few words about the game myself.
The art in Sunrise is fantastic. The designs of characters are very well done. And in general the whole style is very unique. I think rarely can you run into Visual Novels with style like that still.
The story is very interesting and as a reader you definitely want to continue to know more of the story. And the twists are really well thought.
I played the game on Youtube very very long time ago and all the videos are put on Sunrise playlist.
