flOw is a mesmerizing game of primordial life, evolution and survival. Dive deep into the wild blue to seek out and consume other organisms on your path to simple cell nirvana. Begin life as a microscopic multi-cellular organism with a semi-circular shaped 'head' for feeding and for locomotion. The organism moves by following the mouse cursor, moving as it moves and always in pursuit. Click and hold the mouse button to accelerate its movement, though doing so will make it more difficult to steer and to make sharp turns.
The starting location is at the top of a very deep pool, 20-levels deep. The top level is indicated by the game's "flOw" logo, which can be seen when the game begins. On the top level you will also find another organism with a small red dot "." in its middle. This organism can be found on all but the deepest of levels, since eating it will take you down one level. There is a similar organism with a blue dot "." on all but the top level; consuming it will take you up one level. If either of these two creatures ever leaves the screen of the current level, small ripples, in corresponding red or blue, will appear along the edge in the direction that it can be found. Just follow the ripples as it is also an indication of where there may be food as well. To eat another organism as food, for example one smaller than you, simply navigate your creature so that the 'food' comes within its circular 'mouth' and it will consume it. In later levels where there are even larger organisms, steer for the bright circular shaped cells within the body cavity. When an organism (including your own) loses all of these life-giving cells, it will perish.
Continue your advance deeper and deeper to discover what lies in waiting within this absolutely magnificient piece of interactive art.
