Oooooh, gotcha. No, I couldn't get to finish the game, even while being able to reload (you might want to add that into the instructions in your page), I'd need some more hitpoints for that, or a way to get more hitpoints. I could just barely kill the last enemy far to the right with three of them :D
Also, what I meant with 180 was to be able to shoot in any direction by pointing the mouse at where you want to shoot, instead of being able to shoot either to the left or to the right.
