Mercury (PSP)

From the mind of developer Archer Maclean comes Mercury, a puzzle game that lets you guide the metallic substance through a series of challenging puzzles. Without spilling too much, you must control your colored mercury blobs around 3D mazes simply by tilting the level. Negotiate obstacles and hazards, solve puzzles, and compete against time and percentage limits while avoiding traps and predators. In addition to the single-player mode, Archer Maclean's Mercury also features multiplayer battle and ghost modes.
