this game is mad fun!!!
I love this game!! Rarely will I get this into a flash game and rarely do I ever save one to replay except as an example of a particular programming technique I want to learn or something. This though -- I'll be playing over and over for a while.
I really have no suggestions as to how you might make it better -- well, maybe a few variations on the weapons but simplicity means playability so I think its great as it stands.
Awesome flash dude! STRONG 10/5!
