Osmos/Ambient

In the ambient levels, the player's mote typically floats in a large area surrounded by inactive motes, and must become the largest or simply very large. Variations on this theme involve, for instance, starting the game as a very small mote surrounded by lots of larger, fast moving motes, or the presence of "antimatter" motes which shrink normal motes during collision no matter which one was originally bigger, or starting the game stuck in a huge, densely packed area with a large number of other motes without much space to move about and having to nudge other motes out of the way by ejecting mass at them.
