6 for art. A lot of the characters looked very similar, and could be hard to tell apart.
7 for sound. granted this anime has a big soundtrack, the songs matched well.
7 for character. You grow to like certain characters, and become attached.
10 for enjoy. This is an opinion based answer, but for me with the story, and the sounds it was very enjoyable. especially watching all the alternate endings so you can find one you like to match to the story.
Overall this is a very good short anime.
