Amazing
This movie has an incredible strong story.
This is the quality of story that I use to see in the cinema.
Also, it has a good potential for future episodes, eg you could develop/show more of the character's personality (which have been taken care for, those character maps are a amusing and interesting. No doubt, this episode contains enough to introduce them.
Don't worry about the soundquality, it quite an outstanding work, as are the graphics. I can see the care taken for synchronisation and I can apreciate that.
Nice work are the fighting scenes, very acurate drawing with a nice speed.
In my opinion, worthy to become one of the permanent series of Newgrounds.
