Shoot'em Up

I figured that since there are already tons of Shootorial creation games out there, i might as well submit mine. It is just a simple game where you are protecting the world from evil creatures. This is my first flash creation built using the Shootorial tutorial. It has 2 base enemies w/ mini-bosses and big-bosses. Be sure to read the hints and tips in the directions page. they are very helpful. Graphics are taken off of google. I don?t know what or where they are from and this is me giving them credit.
