Then Brad takes a look at Mercury Meltdown, and comes away less impressed than last time:
"Although the first Mercury on PSP didn't set the world on fire, it was a unique twist on the traditional "rolling puzzle" game with its own unusual charm. I grew to admire the physics of sloshing liquid metal through clever setups, and the abstract aesthetics of its shimmering sheen appealed to the art wonk in me. I would have been quite satisfied with more of the same from its sequel, Mercury Meltdown, but was disappointed to find that it strays too far from a formula that wasn't entirely solid the first time around."
