Limited Invincibility

In Mission 2, go to the destructable box up and to the far left from the starting point. Proceed to the left until a little shiny bit of the box is showing. Destroy the box with an arrow, making sure there's no enemy soldiers on the screen. As soon as there's an impact, walk left as far as you can with a trail of smoke behind you. You will be invincible until you reach a bonus stage where you can be killed, or until you destroy another box.
