Good stuff!
It better not be a "probably" coming out. With how well you animated just about everything, it should be a "definitely" coming out... that is... if you think you've got enough original content to put it out. But, then again, this is the first piece of work I've seen from you, so we can't really tell yet, can we. I do think you're going in the right direction, though!
Quick pointer. Right before sonic breaks in to the cockpit, you slanted the sonic sprite in a way that was just... too much... I mean, you were doing such a great job with the smoothness and the camera angles, and then that happened. Not saying it was necessarily a bad thing, just was sort of like me screaming "AW, CMON! YOU KNOW YOU CAN DO BETTER THAN THAT!"
Can't wait to see your writing and story-telling skills be put to the test! Lemme know when it comes out!...and I just noticed something in your comments. You say "Expect future battles to be much slower." I hope you don't mean the motion speed, because that was just where it should be!!! DON'T YOU DARE MODIFY THAT! Less one-sided? Ok, that sounds better! =P
4/5, 9/10. Keep it going!
