The weapons, and having random variables rolled for them was solid. The art looks good and sfx fit.
But why do you got these GIANT BORDERS taking up so much screen space? Game really needs to be zoomed out. Horizontally is.. okay but I wish I could see further, and vertically its terrible. You have barely any perception and so you can't tell where the things shooting at you are or where you are suppose to be shooting.
I think if you improved the camera, it'd significantly improve the experience.
