Nice work
It was done well... There were a few moments of spelling errors. Sonic says "Pick up the pase" when Tails is holding him... it should be "Pick up the pace." Also, Knuckles kicks a$$. And i think there is a scene where the word "immediately" is spelled without the "e". Where did Tikal come from? I've seen Sonia before on that crappy Sonic cartoon. My favorite was the really dark Sonic cartoon that featured Eggman turning everyone to Robots and actually sort of winning. Forgot what the series was called.
But still, nice work.
