Just a bunch of bouncy balls that grow when interacting with the edge but shrink when interacting with other balls. Use the S slider to amplify the speed of the balls: 1 (Fastest) And 5 (Slowest). To turn on S and show remaining blue and red dots press Space key and to hide press 0 key. If a ball is too large it will die and make 2 new ones. Making the battle last longer
