Released in demo form late last year, Auditorium is an astonishingly clever music-based puzzle game. The full version is now available for purchase, but you can still check out the demo.
You direct coloured waves of sound to containers scattered around the screen, filling them up to build the overall musical composition. Not only does it look gorgeous, but there's so much room for creativity and simply playing around with how each tune is composed. As the developers say: "Auditorium is about the process of discovery and play. There are no right or wrong answers; there are many ways to solve every puzzle." It's ideal for a Friday afternoon..
