See how many times you can shoot before you shoot yourself!
The blue circle is a shield. Once it gets shot 5 times it goes away and you have to wait till it comes back. The shield will be placed randomly throughout the game.
When your "metal" bar is full you can't be killed. Bullets will just go away when they hit you (they will not subtract from your score).
