Amazing
First thing, voice acting, superb. The characters all have personal motivation and show it perfectly. The story is creative and the drawings are unique. This flash is amazing by far one of the coolest I've seen. There's only two things that were not as perfect.
Sometimes the voices sounded as if they were in different areas, which can be hard to control due to not everyone's mic being the same when recording audio. But it's easy to shrug off, and the other, I noticed in the combat scene there seemed to be a few 'missing' sound effects for certain movements, like a ball of energy between two hands didn't have an effect at all or some blocks etc. I know getting sound effects is a pain in the ass to get for free so I won't take my overall rating down ;)
Keep it up, the story is interesting I hope you continue on with this flash and if it gets boring for you and makes you think about not finishing a sequel, do something in the flash you enjoy doing cause we all really want to see a sequel! lol
