I've been waiting for someone...
...to make a NEW Super Mario Bros. flash, and if I may say so, you did a smashing job, old chap. ^_^ Nice to see you keeping up with the times and not making another 8/16-bit sprite flash, as there are way too many already. I liked the amination of the characters. Very smooth. The funniest bit was that Koopa's face when Mario farted. Great job. Keep on flashing! =P
