This could have been a classic flash movie if you worked a bit harder on it.
First of all, the sprites are too small, so that it's a bit hard to tell what's going on there. Try using bigger sprites or resize the sprites to something bigger.
That way you could also work with facial expressions, thus adding more content to your flash.
Also, don't use all black text on a dark background as it is quite hard to read. I misread "you've" as "you're" at first glance. Either use some speech-bubbles with white backgrounds or use some subtitles.
The best solution would be some voice acting, but this is quite hard to do.
The gun Luigi used to shoot was ridiculously oversized. It was nearly as big as Luigi himself. You should put a bit more effort into your flashes and try to get all in corresponding sizes.
What hurts this movie the most are the "bullet holes". They are just plain red circles, which looks very bad. It also didn't look good that Mario and Yoshi were just standing there after being shot. Try manipulating the sprites a bit more, maybe with some gore effects like heads being blown off and slumping down bodies.
Last, but not least, I think the plot needs some work. Why was Luigi shooting everyone? Yoshi making some strange noises hardly can't be the reason for that. So show to us that he gets sick of being a janitor with Luigi ranting while he's doing his job or maybe he has a really bad day where everything goes wrong and then he just can't take it anymore.
