So, I don't know about anyone else, but when I try playing it (in Firefox), I spend the entire game rotating clockwise. If I don't touch the mouse, it's just a slow rotation; if I turn left, I can kind of stop it briefly, but it makes it awfully hard to aim. And to not get shot.
I don't know if it's just a browser problem, but it definitely rendered the game unplayable. Which is a shame, it looks like there's a pretty good game in there.
