Damn good
Good game, but for future reference here's a few things that might improve it (from one Flash developer to another):
Being able to see the position of the mouse would help. It's easy to go outside of the Flash movie area and then you lose control of the arm. If you could see where the mouse is, even just as a little cross, it would help prevent this.
The gun shots are possibly too loud, they drown out the music.
It's quite tricky to pick up the guns, although this is probably related to the mouse-issue. When you try to move the arm down wards to pick up a gun the mouse goes off the Flash movie area and so clicking doesn't make any difference.
Still, it's a bloody fantastic piece of programming and really does deserve it's high rating. Nice one.
