Great job. Good visuals, sound and music. I think the projectiles could have been a bit faster and thus more accurate but it worked with the tone. My weapon got so huge and slow I couldn't keep up with all the enemies. I suppose that's intentional but a bit counter intuitive. Having some additional mechanics to the gun and movement would make it even more fun. Something like Devil Daggers is an example of a small arena shooter with lots of things to do.
