Your goal in this interesting flash game is to protect the big ball. Use YOUR MOUSE to swing your ball and try to hit the black balls to keep them away from the big ball in the middle. If the big ball leaves the boundary, you lose. The harder you hit the black balls out, the more XP you will collect. Spend your XP points on upgrades: speed, size, big ball size and boundary size. Every 10 levels there is boss, keep on smashing him until her runs out of health. Enjoy!
