great flash, but here's my analysis...
one of the problems I noticed was that several voice clips seem to clip, reducing quality. another problem I noticed is that the pace is also a little inconsistent, there are moments when the pause on a character is too long. shorten this, and it should reduce the load time as well as possibly helping your score. And what was up with the metalix inching after amy? they seemed far too sluggish getting to her, almost as if for the convenience of Sonic.
What I did enjoy was the fight scenes and how well a certain character of mine was portrayed. keep all the notes I have given in mind and you will get a higher score from me.
