This was really something special
This is a triumph in flash animation.
Everything - animation, art, voice acting, "camera" angles - was top notch. Even the choice of blue as the dominant outline color, accentuating the cold and isolation, was perfect.
At first I thought this was going to be a run-of-the-mill zombie outbreak story, due to the alert broadcast. Then you begin to wonder if this is a tale of insanity, another over saturated theme, but the dog smothered that idea. It leaves you in wonder and suspense until the end, leaving you in an even greater state of bewilderment. I couldn't ask for a better conclusion, which is to say, no conclusion at all.
Bravo to everyone involved.
