This is too short, and doesn't use transitions very well. I see you've tried to make a menu where one can select between different clips. However, it would help to label them as opposed to simply clicking characters. Also, when a character shoots a shotgun, he should take a step or two backwards. Additionally, guns should move up a bit as well as backwards when fired. When a character falls down, there should be a bit of a bounce after hitting the ground as opposed to simply falling flat.
