uuuuummmm i Love it but i will LOVE IT if you upgrade it more: u can just shoot in an endless circle of bullets and they will hit a baddy sooner or later so you might want to reduce screen size or sumthing. You definitely make baddys harder as u progress along the game, DEFINITELY make upgrades E.G shotgun bullets, more armor, buy lives etc using money u get from killing opponents. I cant wait to see if u upgrade this game if u do then it will be even awesomer! 4/5 from me.
