Mercury provides an addicting challenge through its simple gaming mechanic, which merely requires players to 'tilt' each level in order to manoeuvre the blobs of mercury, with various switches, platforms, obstacles and hazards standing between level goals.   Powering Mercury is a ridiculously sophisticated engine which calculates every gloopy part of the liquid metal as it bends and melds around everything in its path. As the digitised mercury smoothly ebbs and flows under such simple controls, players experience the purest form of gaming imaginable.
