awsome
that was well animated and great drawings
but you need a preloader like the guy below me said get the preloader from this site and for the replay button
goto your very last frame create a button after that click on your button goto action scripts and type in the following
on (release) {
gotoAndPlay (Insert frame number here);
}
where it says insert frame number here put 1 and that will take you back to the start of the flash anyway you should make another one :D
p.s make sure the frame your buttons on is on stop stop;()
