This is one of the better shooters I've played in a long time. The backgrounds are obviously static, but they're still realistic and detailed, and the way you move from the recoil, and the camera spans from left to right, makes it seem like the background is much more dynamic than it is. The Game Over scene with the camera tipped is a realistic touch, and the game itself is fun to play. Plenty of foes and power-ups, and variation in the levels. Nice work!
