The game Dual inspired the story of the water boy and the fire girl. This is an easy-to-understand and very interesting game! In the game, you have to control two spheres representing two opposing forces: water and fire.
Your survival depends on the hardness of the two spheres. They work together as a dance and a song between two creatures who feel empathy for each other. The rules are simple: you have to handle two balls at once, stay calm, and see what happens.
