Well...
I'll tell you one thing. This does not need to be 9mb. I've been dealing with compression in Flash for years and you could easily get this down to 3-4mb. All with sound! Cut your music, don;'t use mp3's use WAV's. Flash compresses WAV files much better than mp3. Stream your sounds don't leave them as events. The fighting was pretty good but it;s too remniscent of Super Mario Bros Z which is ok but I like to actuall see what's happening not crazy fast movements. Keep it up bro you have a good future in sprite animation.
