Flawless.
As I continue to watch it, I can't see anything wrong in this flash movie. Perfectly animated graphics, some humorous parodies to the Final Fantasy series that are also a reverent homage to them. The battles are built in the exact style of a JRPG, with even the typical explanations of weak points.
I'm quite a foreigner from Japan but I can say that the voices not only have a good pronounce, they also keep every inflection of the japanese language.
This has to be on top of Newgrounds charts for a long time. Just because it's one of the best movies ever made in Flash.
