Shift-click the green flag to enter turbo mode. The square is a source of food. Dots too far away from it will die off, while nearby dots will grow and divide. Dots also receive more or less food based on how much they match the color of the food. Drag the food color slider or drag the square to change the environment of the dots. Changes that are too fast will lead to extinction. If all the dots die off, click the green flag to reset. Change the weights of the factors at the bottom to change how much they influence the growth of the dots. Factors with low weights are unimportant, while factors with high weights are necessary for survival. The population factor causes less food to be given to each dot when more of them are alive.
