Auditorium has done well as an iOS app and a web-playable version, but a Steam version will be a welcome addition to the roster and should definitely help spread this intriguing game to a wider audience—as unique Indie games tend to do well on the platform.
Auditorium is an exploration of music, light, and color. There is a stream of light coming from off-screen and you must drop objects in its path; the objects redirect the stream in various ways. Your goal is to direct the light into music bars; as you send more light into the bars, orchestral music flows out of them. It’s soothing and it gets relatively challenging in later levels as complications are introduced.
When Auditorium becomes available on Steam, go add it to your collection; you won’t regret it.
