Auditorium

auditorium is an online flash-based music game.
The idea is to direct the flow of particle streams to "fill up" some auido level meters. By doing so you increase the volume of different audio tracks and produce a finished piece of music to complete the level.

The game uses flash-based audio and so this side is not brilliant - it only plays audio loops and these are quite obvious when they loop.
However, the game is still only a prototype and so the audio side of things may well get better as they developers continue to work on the game. Visually it's very good!
