First off, I've got to say, this is a really fun game. Reminds me a lot of one of my top two favorite computer games of all time, Escape Velocity.
I haven't read through all 100+ pages of comments, for forgive me if it's been said before: I'm using Flash Player 10 on OS X, and while the movement and turret control has been no problem, the scroll wheel on my mouse (which, according to your game should change the zoom level of the radar screen) just scrolls the page up and down. I understand that I can use the buttons, but in the heat of battle as it were, they're just too slow. Maybe you could map the 1-0 keys on the keyboard to different zoom levels or something.
