Mercury Hg expands on the addictive qualities of its predecessors, crafting 60 all-new deviously constructed levels filled with hazards and obstacles while adding improvements and polish to almost every aspect of the game. The 'Mercury Blob' is still as mesmerizing as ever, moving uniquely under player control, changing color in order to progress through the level and dividing if cut by a protruding surface. While this dissection is important to solve puzzles, the real test of a player's skill is the ability to navigate strategically through varying types of slippery objects and sticky tiles with the use of balance and momentum in order to get to the finish line with their blob fully intact. A scoring system with full online leaderboard support adds a competitive touch to an already engrossing single-player experience. Additionally, the blob and game levels pulsate and react to the in-game music or songs from the player's library in real-time.
