I just stumbled across this gorgeous Flash game called Auditorium. The idea is to direct the acoustic particles to the correct audio meter using various tools, but it’s very challenging and there many solutions. Five minutes and I was hooked! Give it a try.
[Update - Oops, it's only a demo at the moment with a full game to follow soon. The creators are also looking for beta testers if you're keen.]
Auditorium is about the process of discovery and play. There are no right or wrong answers; there are many ways to solve every puzzle. To get started, fill up the first audio level. We hope you enjoy the demo of Auditorium.
