Honestly, that was good stuff. If you made a series out of this, I'd definitely find a place for it amongst my favorites. There could be a huge story behind this :]
Anyhow, I'd really like to see you continue this work if you could-but as for the actual flash, it was very enjoyable to watch.
But if you expect people to believe that humanity is falling to wolf demon things, just stop now ;D
Defiantly a good flash describing how music can help you in many ways, for this eg. Fast-paced music could motivate you to do stuff hardly anyone else would do. Again, excellent work.
Could start a nice SF
You hit a fine balance between story and action. It has this exciting feeling of "this could really happen in future" you can find in good SF books.
The "hero" is extra strong and has lightning reflexes, but he raises questions among normal people because he seems crazy (and certainly is !).
The "hero" does slightly impossible actions. Enough to let the viewer think "amazing" yet being plausible because of the headphones.
Apart from that, animation is correct, even if art lacks a bit. Sounds fit nicely. And again, I think your best achievement with this flash is this nice plausibility feeling.
like "mirros edge"
