At the top of your screen, you will see how many lives you have left. The bar shows you how much strength you have left before you lose a life. After you kill each enemy, eat the sushi that they leave behind to give yourself more strength. Pick up ninja stars on your way to the Temple and when you get to the final level, pick up the Jars of Strength to help you defeat the Queen.
