Good but not great
First of all, I'm glad to see that someone has put some effort in making a movie! The graphics were okay, not top-notch but very acceptable. Just like the sounds, which get a bit repetitive after a while, but hey, it's a shootout! I liked to see it, although there is room for improvement (as there is always).
I know you've tried to keep down the filesize, but a soundtrack (even a short loop from time to time) would freshen things up for sure. Also I'd like to see some facial expressions in a possible new version. Finally, this movie needs some kind of plot, a story of some kind. Even if it's only a short introductional (is that even a word?) story to this shootout.
So far my views on improvement, just keep 'em coming and I'll be watching!
