The idea is good, the graphics are good. The thing is aiming is difficult, with the revolver mostly they rivals would move the moment you aim at them so it's not accurate, you need to click mostly randomly. With the thompson, automatic fire by holding the mouse button isn't working, just wastes bullets so you need to click fast and randomly just like with the revolver, you just lose bullets faster. You should have more bullets and restore health at the beginning of each level. The movement of the rivals should have been more realistic, not just motion tweenings. And I noticed even at rookie sometimes after seeing a rival falling dead, he just keeps moving.
