I started playing the game expecting to find a simple shooter, instead I was surprised to find a bit of complexity regarding the gameplay, like different weapons, the ability to use an helicopter and some tactical approch to the action. I wanted to see some differentiation regarding the background instead of the flat color, and I am not fully convinced about the design decision to shoot beyond the screen edges, that can make projectiles hard to avoid. I can say that it was definitely an intersting and enjoyable shooter!
ya sorry I just got lazy with the background, I guess I'll work on making it more complex. Also just to let you know the bots can't shoot you when they are outside your screen (unless on nightmare mode). Thanks for the feedback and I'll tell you when I implement your suggestions!
