Story
For me the story was kinda lacking because some if not all was rushed to accommodate the whole story in just 13 episodes. But the delivery of the suspense for the upcoming scenes are done just right.
Art
Artistically speaking even though I am not an artist myself the art style was not a masterpiece but it just gives the atmosphere of the story. Although they did some changes in the presentation in order to accommodate a general audience.
Sound
The voice actors/actresses portrayed the character as somewhat lackluster. Maybe in the sense that it was just a conversion of the game itself into a series.
Character
The characterization was lacking because they did not give the audience a background for each characters(interest, fears, etc.). To me that has a heavy role on the story on why they would do somethings in order to achieve their goals.
Enjoyment
Although I said so many negative comments above, for me I enjoyed the series. Maybe the story was lacking but the thrill for each scene kinda pumped me up for what is going to happen next. Maybe they hit my soft spot for thrillers and detective stuff for me to enjoy the series.
Overall
I felt that what happens in the future maybe they would deliver much better version of what they were lacking in this series.
