WHAT'S THE STORY? Sequel to nifty PSP puzzler. Glide blobs of liquid metal across obnoxious assault courses, getting your pants in a twist over its addictive, hair-ripping shenanigans.

TECHNICALLY SPEAKING: Physical puzzle game, slightly reminiscent of old classics such as Marble Madness and Spindizzy.

HAS GOT: Incredible physics. Two-player wireless games. 160+ dastardly levels. Gameplay that might make you smash your PSP.

HASN'T GOT: A GTA-esque ability to bang prossies down backalleys and then steal all their cash.
