Quite wonderful
Despite the lack of dialoge, and what was there was thankfully short (although a bit...odd and...well, I didn't like it so much, as it seemed uneccesary (the greeting of "capt. Toad"))
regardless, this was elaborate, smooth, and well 'sprite-d'
Much effort was put into the smoothness, that's it's shinning factor to be sure. The voices fit Luigi well enough, although Peach and Toad were... less admirable. Some 'cheap', as some call them, blur dialoge effects were oddly placed, but made no major impact.
All in all, I could find no pressing technical error with the flash itself, and it's clean presentation, frame-rate handling and action make this an easy choice for a solid 8 out of 10.
the sprites were slick and so was the animation, however, the plot was a touch dry as compensated by all the wonderful action. Certantly note-worthy to the extent of fast-paced action, but as far as story goes, I liked the idea of 'boo' inhabiting him, I'd like to hear more of it overall.
Otherwise solid, and perhaps him being infected with 'boos' (booze?) enraged him? Perhaps coincidence, but a funny one to keep in mind.
Great work, well worth a watch, maybe even twice. Good work. Excellent presentation.
