The levels are set in enclosed environments where zooming can be done freely. After a few tutorials levels, different paths are offered based on variations on the concept. Some of them are based on aggressively tracking another organism or surviving in a crowded environment, another set is about an orbital course floating around a large object, and the final one is the slowest where there is very little space and the area needs to be captured with caution. In levels with limited manoeuvrability, time can be speed up or slowed down to prevent losing too much fluid when going slowly. Levels are usually won by capturing a specific organism (there are many, with different abilities) or growing to a certain size. In later levels antimatter is introduced, with the opposite effect or regular organisms.
The gameplay is supported by soothing, ambient electronic music.
