This flash is WAY too slow. It could be drastically improved if you just bumped up the framerate a bit. I only sat through the whole thing to give it a fair score.
Graphics-Sprites. Some badly edited.
Style-It was ok but, once again, FAR too slow.
Sound-Not so good. Normal Mario music, but there was absolutely no transition between the song other than *STOP* (Silence...) *GO*
Violence-None except the Toad thing at the end. If you improved from this flash, that could be fun to watch :D
Interactivity-A preloader (that didn't work right) and a button after the note from Bowser.
Humor-For the Toad part at the end.
It would also be nice if the story was actually in the flash itself. Most people don't read the comments, but luckily I did before I watched this because I would have no idea what was going on otherwise.
Keep working, and good luck in the future!
