In a way this could be the story of the game are osmosis, if there is one there. The player takes on the iPad a blue ball in the middle of a viscous environment again. The goal in each level remains the same: other blue spheres to absorb contact and grow thereby. When the mass has become now larger in size balls trumps other color, they will be blue and vulnerable for us. This is also true vice versa: If a blue object that has become just by chance on earth and grows beyond us, it turns again and can in turn eat us.
And then control worked exclusively on two factors: thrust and counter thrust. This also applies to osmosis. Through taps on any side of the cell triggers the formation of ground ball and gets in motion. A tap on the opposite side again slows the ride again. The output of the bubble-shaped tissue but leaves the main body shrink - so it is economical approach announced.
Due to the fast driving like bubbles, which act as exhaust by a fired in the will, come from his cell, floating motionless in motion. So one can maneuver through some levels that are completely at a standstill at first appear. Here, gentle insertion of thrust and counter thrust, the entire collection of cells in slow motion moved by.
