Well, I can see you have no lack of self-esteem...
I could have forgiven the abyssmal sprite animation, the poor writing, the bad art, the irritating soundtrack, and the bad grammar.
However, I was disturbed at the manner in which you responded to the reviews posted by other users. That is unforgivable. Your replies were reminiscent of some of the hopefuls who dissed the judges on American Idol after blowing their audition.
If you post your work, be prepared to take criticism like a man. For the most part, the reviews were well-intentioned, and they were generally accurate.
This was not good work, and your art could use improvement.
You wrote "until you do one, you'll see why there can be errors in every flash", by which I presume you mean that it's easy to make mistakes. Yes it is. There is a steep learning curve, and making an effective and entertaining animation can be difficult.
No one grudges you the learning experience. In the meantime, you should learn to accept criticism with better grace.
