Drag to make walls
This is a fun game of illustration on how to keep the population from spreading virus disease. Each white ball is represented as a single person. A sick person or the green colored ball will suddenly come and blend with the crowd and eventually it will infect all the other balls. Your goal is to stop the spread of disease by putting the infected ones under quarantine by means of the walls. Try to get the high score as population will increase as level progresses.
