Try to keep your green ball in the square for as long as possible. Red balls will constantly try to bump you out. But, orange balls are even more dangerous. Once their timer reaches zero, they explode, unleashing a powerful shockwave that will knock you right out of the square if you are too close to the edge. You will also earn ore points if you can stay in the small, dotted-line "quad" circle. When you are in that area, your points increase much quicker. Once you get knocked out, the game is over, and your score will be given.
