It didn't cut it
You had a halfway decent storyline but i could hardly follow it, heres a list of all I found wrong with this move:
No preloader, for a 9.9mb flash you really should use a preloader, and newgrounds offers them for free
All sprites were in jpeg format, this is a big no-no in sprite movies, use .bmp or .png formats
Text was nearly impossible to read, make your text clearer next time
Animations were extremely choppy, it looked like it was made with windows movie maker
Story was hard to follow, all I got was Sonic went Super Sonic, then lost his power, Knuckles made him super again, then Mecha Sonic went into a container beside the Master Emerald [which you mistakenly said Green Chaos Emerald], then tails getting knocked out by super Mecha sonic and the same happening to Knuckles, then Super Sonic found a goal ring which exploded, then somehting about Super Mecha sonic draining Super SOnics power to kill him. A very confusing storyline
Endless loop, the movie loops endlessly
Most animations stop when characters speak, people generally dont freeze when talking
Different style of backgrounds, you keep switching between sprite backgrouds and photographs, keep it sprites or photographs but dont switch between them
Opening eyes part, sry but that was very poorly done, and the bars kept moving at the start which did not help at all
Overall, I give a 2 for effort, but these sort of movies are for Youtube, not Newgrounds
