Damn it!
It pains me to have to give you less than ten, because this is so close to perfect. However, there are some problems that I can't help but notice;
Firstly, the characters take too long to do some actions. When the demigod is running along the trail from the energy blasts, it feels like it takes FOREVER. The same thing when he is being blasted by the Leviathan or whatever it was; repetitive and irritating. I don't mind shorter animations, especially if it takes out that problem. It felt like padding and a little bit of laziness as well. On the other hand, the animation was fluid, pretty, and worked for the most part. Excellent music as well. Hopefully this can all be fixed in the future.
