Duet is a hypnotic arcade action game with a mesmerizingly beautiful soundtrack by Melbourne composer and Gotye multi-instrumentalist Tim Shiel.

Elegant and minimal, Duet asks players simply to navigate two orbiting spheres past an increasingly complex maze of falling obstacles. As the difficulty increases, the tension mounts, and a peculiar narrative unfolds.

Tim Shiel is a composer/producer based in Melbourne. Tim is known to some as Faux Pas, the moniker under which he released a steady stream of constantly shifting electronic music for many years. He is also known for his work as a broadcaster at Melbourne independent radio station 3RRR FM, and for his recent role as multi-instrumentalist in Gotye's live band. His passion for gaming and his fluid approach to composing have led him to team up with local game development studio Kumobius, to provide the soundtrack and in-game sound design for their minimalist new mobile game, Duet.


Duet has been an incredible success for us so far both critically, commercially and personally. The game’s narrative has resonated with players and we’ve blown away by the response. We received emails telling us how the game helped people think differently about the world and helped them get through tough times -- this is something we never imagined our game could do. Tim Shiel conducted a live orchestral performance of Duet in Australia in which tickets completely sold out. Lastly, it has been our most successful game as a studio so far with revenue now in the 7 figures range.


  • Over 140 challenging stages full of elegant obstacles and features to keep you on the edge of your seat.
  • An outstanding soundtrack by Tim Shiel, his debut to the video game world.
  • Simple two touch control – left or right thumb to spin.
  • Entrancing visuals fit the mood and audio of the game perfectly.
  • Unlock an endless Survival mode for high score delight.
  • Strange and wonderful narrative that will keep you guessing.
  • Every mistake leaves a mark; you will paint the walls with your failures.
