Sentris

Sentris is a music video game where players solve puzzles by composing musical loops. Following a successful Kickstarter crowdfunding campaign in October 2013, an early access version of the game was released for Linux, Microsoft Windows and OS X in August 2014, with an official release in August 2015. A PlayStation 4 version was planned, but it was never realised. An Ouya version was in development, until the Razer acquisition rendered the contract void.
