For an anime released in 2013, it looks really good and could give some modern anime a run for their money. However, the art style in certain scenes does reveal its age and during dramatic moments the brightness is amplified to the point of being mildly disruptive. As for the plot, it does a good job of explaining the world on a surface level while also establishing the protagonist's main objective. The soundtrack is good, although the OP isn't really my cup of tea.
