Sorry but...
It was WAY too slow to watch, let me give you some examples.
-The opening scene took about 4-6 minutes
-When the 3 new robots were introduced, they were posing for about 5 seconds
-Megaman and Dr Light were talking too long
-Centaurman was did his pose but it was like he was delayed
-Megaman was using his laser blast and he destroyed the robots, yet after they died he laser blast was still going
Also the grammar needs work, if you are not English speaking then I respect you for writing in a different language, but if you are English speaking then you need to do more literacy work.
If you are doing spin-off sprite movies of your favoured character then you should know that your movies need to be more intense and fast paced, I've also noticed, you have to research other successful sprite movies and see which features make a flash movie much more enjoyable, and look at your movie and see what they did that worked that you didn't, but not to plagiarize, of course you need your own style. A.Earthworm uses alot of intense battles and humor that fits, OK he does tend to overcrowd his battle scenes, I know he struggles with 1 on 1 battles but he covers that flaw by making the other departments of his series so brilliant. But the main thing needed for you to do is increase the pace of the movie in every area, from fights and battle scenes, to introductions, presentations and conversation, that is the only thing stopping your movie from being brilliant
