I'm currently sick at home and I don't have the mental energy to do anything useful but I actually found this oddly amusing and mesmerizing ... Because you shoot so quickly and turn so fast, I found that you can just hold down the spacebar and turn around to use your stream of projectiles kinda like a whip, turning left and right to get the curvy stream to intersect with the ships. This also defeats most of the right-in-front-of-you spawns. Anyway, very neat!
