Transient Nova from Genuine Gamers reviews Mercury Hg on Xbox Live Arcade:
"How many scientific elements can you name that can actually serve as sound gameplay devices? Not a lot I would imagine, seeing as most of them are quite boring when left on their lonesome. Plumbers and hedgehogs make it a point to collect valuable gold substances at most opportunities and lead makes itself known in just about every first and third-person shooter known to man, but what else is there apart from that? I wouldn’t really know admittedly, especially considering that I only look at that table periodically anyway. Thank you! I’ll be here all night!"
