meh
I liked the concept, but the aliens kill you with a single blow, no health at all, and the aiming is kinda tough when your bullets fly right thru the enimies, it makes it kinda frustrating... gimme a targeting reticle and a health bar with refills and its be a lot better, graphics are good, and the idea isnt exactly original, but at least you got a new twist to it, and your own aliens
But definatly, Definatly add a targeting reticle and a health bar, then youve got a serious winner
