An emergency has happened in Fairy Town. A huge ball appeared in the sky, and around it along the perimeter there were many small multi-colored balls. This structure blocks the sunlight and if this continues, the city will plunge into darkness. No witches, magicians and wizards can do anything. The only thing. What they suggested was to build a cannon and shoot all the balls. The cannon has been built and set up so that you can move in a circle shooting the balls. Now the fate of Fairy Town depends on you.
