Not bad, but with bugs.
Not bad in fact. But I faced 2 problems:
1. It's hard even to start the game. I have a trace of targets after my cursor on the initial screen, while real crosshair-cursor is staying at the top left corner, and "New Game" button is not pressable.
2. Sometimes I receive errors from Flash Debugger (I'm using Opera browser) while trying to shoot the targets: "TypeError: Error #1009: Cannot access a property or method of a null object reference. at target/frame16()". After closing the debugger window all previous targets disappear and I get a set of new ones.
