Players control a circle that must navigate a pond filled with water-dwelling creatures. The goal is to collect a school of fish while avoiding obstacles and predators.
The core mechanic involves using the circle to swim through the water, dodging or blocking fish that come into its path. Players must time their movements carefully to collect the fish without colliding with them.
The game takes place entirely in a web browser, without the need for a download or registration.

The game challenges players to adapt to the ever-changing environment, where the placement and behavior of creatures can shift with each new attempt.
