Auditorium
In Auditorium, the player uses various game mechanics to bend streams of light particles to fill audio containers. When an audio container is filled, an audio channel containing an instrument or sound is added to the game's music. In most levels, the audio containers have different colors that the particle stream must hit to fill them. The player changes the color of the stream by steering it over specified areas of the level, which the particles color as they pass through them. The goal of each level is to direct and split the stream of particles so that all the audio containers are filled at the same time, revealing the entire soundtrack of the level.
