Each eliminated bacterium earns the player one point, adding to the competitive nature of the gameplay. The objective is straightforward, making it accessible to a wide range of players while still providing a challenge.

The game features a simple yet effective design that focuses on quick reflexes and strategic clicking. Players must be wary of the time limit and the possibility of the grid becoming filled with bacteria, as either scenario results in game over.
