Wow... Just wow...
I'm sorry but words fail me at the moment. This has been the best thing I have laid eyes on in a long time. It actually had me pacing after I was done watching it and then I played it a couple of more times just for the soundtrack. The voice acting was PERFECT. As someone else already stated actions went perfectly with the flow of the music and the thing as a whole just grabs you and doesn't let go until the end or even after. I use the word thing because it's too good to be referred to as just a "flash" yet too short to be called a movie regrettably. I believe many people here along with myself would love it if this was made in to a series or something else that unravels the entire story. A hard task indeed but dreams are free right?
Kudos to you
