Auditorium is an online audio puzzle game and it’s a lot of fun. The interface of the game is very smart, visuals are highly impressive and the game itself is very entertaining. The idea is to set up the scene to have the correct light low in order to get the right melody. It somehow uses a lot of processing (CPU) power due to flash’s weak GPU support. You might want to play in a window instead of full screen or reduce the quality. Anyway, it is a really good experience!
