Waring: Your enemise are all around the Target.
You have tow choices: Surrender immediately, or defeat them one by one.

You will control he black-white ball to move sharp and fast.
All your enemise are malicious but arrogant. Once two of them collide, the die together.
When they reach the black edge or the red center, they die, too.
But once you collide with one of them, or hit the edge or the center, you fail.

Goal: Survive until all other balls die.
Notice: Only the red center and your black-white ball are attraction sources.

(To kill the last blue ball, I have tried several times, but succeeded only once)
