I am a sucker for most types of music game but I don’t think you need any sort of heightened interest in the relationship between music and interactivity to appreciate the brilliance of this three level flash demo for Play Auditorium.

The game’s best understood through experience but, in short, you must position directional arrows in a 2D abstract space in order to guide a stream of particles towards a volume control target.

When the stream of particles hits the target a looping instrument track fades in. By adding multiple volume targets the game and its musical accompaniment builds in sweet complexity. The aim of the game is to get all volume controls powering up to maximum volume, at which point you proceed to the next level.

I love the way in which, as you play about with arrow positioning, sections of the music fade in and out, creating something of a unique sound journey through the level for the player. There are multiple solutions to each puzzle too, lending the game design a pleasing non-linearity, albeit within tight constraints (the best kind of non-linearity).

See what you think and, if you’re feeling generous, throw them a few dollars to develop the idea further. The game even remembers your progress (via cookies or shared objects, I preume) so you can pick up where you left off at any point.
