Little fairies were infected with an unknown virus and are now attacking civilians. Scientists quickly created a special application "Pocket Fairy GO" with built-in radar to detect fantastic creatures. In your arsenal there are red and green balls, with their help you can either destroy the fairy or heal her. Your indicator of humanity varies depending on your actions. Go through the streets of your city or village and aim at the camera of your smartphone. When the radar detects a fairy, throw green or red balls into it. You are good or bad - choose!
