From the publisher: Maneuver colorful orbs of liquid mercury by tilting them through 3-D mazes and moving them in a particular direction around infinite obstacles. It seems simple, but you must take advantage of the orbs while they're still in a viscous state and try not to spill too much of the liquid. With 72 levels, you can also experience this game in two-player mode with PSP's Wi-Fi capability while fighting against time limits and traps that increase with each challenge.
