Yeah, yeah, yeah...
Just to re-state what everyone else is saying- it was too short. Sorry, but I had to say it. Other than that one minor flaw, this flash was fantastic. The music is fast-paced and goes along perfectly with the action in the movie, and the 12-different-things-happening-at-once theme was great. (Even though it lasted 2 seconds.) The end wasn't particularly funny, and when he flattened the goomba, the jump was rather slow, and the goomba flattened too quick to tell what happened to it immeadiately. Other than those two things, this flash was nearly perfect for a fast-paced action.
Animation-9-a bit rough near the end.
Characters-10-Mario,Luigi,stick,goomb a,koopa,hammer bro. Classic.
Concept-9-not the most creative thing in the world, but you pulled it off nicely.
Overall-9-Nice work!
Keep it up!
