I wont lie....
I dont like it and i dont think its worthy of frontpage and in the Mario collection. It can be better if u do this:
1. Try using regular mario sprites, no offence but i dont like that mario sprite u made.
2. Get some sort of storyline. This was way too random.
3. Improve the graphics. Overall, all graphics need improving
4. Improve the sound.
Maybe if u do that and practice flash some more, you can make a better movie.
