Algodoo

a world with wars,dividing,food and hunger.
Small balls of different colors attack each other, and the larger radius ball can swallow the smaller one. After the annexation, the radius of the big ball is equal to the radius of the small ball plus the original radius. When the radius of the ball is greater than 1 meter, the ball will split into two 0.5 meter radius balls. The blue turret makes pellets of food (0.1 m radius).
