NaturalMotion's CEO Torsten Reil announced a new 'interactive toy' called Clumsy Ninja on stage during the Apple iPhone 5 announcement.
The gameplay centers around training the ninja and improving his "ninja skills". The player can train the ninja by doing certain activities such as: playing hide and seek, playing on the trampoline, training with a punching bag and many other activities. As the ninja improves his skills he earns new belts. Another big part of the game is traveling the world and completing quests. Doing so will unlock new items that can be used to further train the ninja and the ninja earns 60 gems.
The game was received with generally positive reviews, with many praising the revolutionary technology behind it. Clumsy Ninja has received an average user rating of 4 1/2 stars on the App Store. Toucharcade gave the game a 4 out of 5 saying: "NaturalMotion has created something very impressive and they clearly want to show off their little Ninja and what he can do".
The music was written by Rich Aitken and performed by Aitken and Ed McClements who both work at Nimrod Productions. The game's soundtrack consists of simple acoustic guitar sounds. Sound was managed by Ed McClements with input from Rich Aitken and Tom Brooks (also of Nimrod). All sound work was done within FMOD. The music was nominated for a MASA international award in 2015.
