Not very realistic. Garbage scowls were never outfitted with photon torpedoes. Well, maybe Klingon ones. They'd put disruptors on their kids Big Wheels, but I digress... :D
Great video demo! This is like a more complicated version of the arcade game Galaga. Smooth graphics, too.
I'm not a gamer anymore, but if I were, I'd definitely download a copy your program.
