Exactly like in the scene this is a response to...

This scene consists of a race of small creatures that jump around, reproduce, search for food, and call the others when they discover food.
Food is limited and is in the green bins.

Perhaps not quite like in the scene this is a response to...

Each circle's health is shown in its color. The darker the circle, the healthier.
A black circle will die unless it lands on food.
All circles carry tracers, so you can see them when they get really dark.
A circle's health will decrease a bit whenever it lands on non-food.
A circle's health will increase some when it lands on food.
A circle will also duplicate itself when it lands on food.
A duplicate circle will also always have full health.

Sometimes, there seems to be an invisible wall right on the goal. If, when circles get there, they seem to jump off something that doesn't seem to be there, please let me know. It happens to me, too.

Above all...

For the Phun version, see the scene by RaRaMalum that this is a response to.
I did not make it, but did get some code from it.
