Very creative
Graphics:
Sprites were the medium, and you won't get any better than Mario.
Style:
The animation was smooth and the concept was translated well.
Sound:
Good use of the two theme songs, as well as other sounds.
Violence:
*Square block falls on Mario* (That's gotta hurt)
Interactivity:
Didn't need it.
Humor:
Interesting idea, funny joke.
Overall:
The idea was executed cleanly and in the best way it could be, despite that being the dreaded sprites.
