A different style from most animations you see out there. Fire like background (3D like) with a totally black foreground and black characters. The characaters and the black lines in the background tend to connect each other to form a new object...(Not like in most animations where the background and foreground are two seperate things, and remain separate). The story makes sense (A bit confusing at the beginning because everything is getting mixed together: Foregrounds and backgrounds) but then as we get closer to the end, we start to understand.
The music is very catchy and it blends in very well with the animation, making the actions and the characters look funny instead of scary. Again the animation style has an attraive point of its own because of the different style.
