Needs Much Work
You're obviously new at flash (or at least I hope), and possibly new at sprites, so I'll give you a few suggestions. First off, try and think of better dialog. If you're going to make a Mario movie, please don't make it that the princess was captured, especially not by Bowser. We've seen it a million times man, and a million +1 is not what we need. Your sprites were'nt horrible, but they were on the poor side. There were many mistakes, such as having a movie clip play when the scene isn't fully faded in, or making the animation of the sprite too quick. Combine that with a sluggish tween and you have some impossible physics (unless the dude's on ice or something). Also, the sound choice was terrible. A single song that loops four dozen times is annoying and undesirable. Pick at least two or three songs for your movies (unless it's a music video). The humor was very childish, and it made me cringe rather than giggle. If you don't think you're a funny guy, then don't try to be someone that you aren't. Stick with serious flashes instead. That's all I have to say, and I hope you take at least some of these pointers seriously. Good luck next time man.
