pretty good!
great job with your voice acting and style-but, in the future, don't state that it is your first flash-some newgroundsers take that as a bad aspect and hit the "blam button" so to speak. which will definitely diminish your deserved score unfairly-happened to me a while back. but great job, you definitely have potential.
My suggestion to improve is to add some actionscript, like make a square, or whatever, and selct it, press "F8" and make it into a button.
then put in the code
on(release)
{
gotoAndStop(1);
}
this will make a re-play button at the end of your flash-essential really.
and you might want to stop your flash instead of having it loop- use this on your last frame
stop();
hope I helped
