Well done.
The sound components, both background music and effects, was exceptional.. The funeral theme was heart touching... it made you so fukking pissed and you just felt angry and wanted to destroy the whole fukking castle, although the scene did drag along.
The flash sequences of the sprites in motion was pretty smooth.. and i guess you can't improve the graphics, because that's what all mario game graphics are like.
Well constructed movie, you put a lot of thought into it. Well done.
