Nice,
Nothing like a movie of Tails kicking ass. However the sound was abit of a problem. Using Shadows voice for Tails hmmm but i know some progrms which you can use to edit the voice of Shadow and make it sound like Tails.
It seems like Tails is losing his mind, Eggman being his first victim in all, a Sonic vs Tails fight would be cool.
Also nice sprites, could you send me a sprite sheet?
