Nazo Waku Yakata: Oto no Manimani

Nazo Waku Yakata: Oto no Manimani (literally translated as "The Mansion of Confusing Puzzles: at the Ｍercy of Sound") is a game which features voice recognition. Although there are some stages which require conventional controls (e.g. touching the bottom screen or press some button), most of the time players need to speak to the Nintendo 3DS's microphone in order to interact with the game.
