The goal of the game is to Pierce all targets, which can be targets of various materials and powerful bosses.
With only one finger to control, click to throw the knife up and spin, click again to launch it. If you do, you lose your life!
If you collect more coins around the target, then you can buy cooler knives, swords and daggers from the store.
With more different targets and beautiful backgrounds, you will encounter a "boss challenge" at each level.
