About the game
Duet is a minimalist, elegantly designed indie action game in which players steer a pair of orbiting spheres through an increasingly intricate web of falling hazards. As the challenge escalates, so does the tension, gradually revealing an unusual narrative along the way. The game was both developed and published by Kumobius in 2015.
