Boreas and Zephyrus is a one button game about two dueling wind gods. Boreas, god of the frozen northern wind, attempts to steer a drifting boat to his icy isle. His brother Zephyrus, god of the warm western wind, attempts to steer the boat towards a tropical paradise. Each player assumes the role of a wind god and attempts to create eddies and currents to accomplish their goals and thwart their opponent. Pressing their button launches their god across the screen, realistically affecting the fluid simulation in the center area.
