Planes contain organisms of varying sizes; the player's creature automatically attempts to consume them when they are nearby. The majority of these creatures are non-confrontational and are composed of cells that increase the number of segments in the player's creature when eaten. All planes, except for the highest and lowest, contain two specially colored organisms that move the player's creature up or down one plane when touched.
This game involves a creature that moves across a series of planes. The creature consumes other creatures to grow, with some being non-aggressive and increasing the creature's segments upon consumption.  The movement of the creature is controlled by two special colored organisms on specific planes.
