You can hear the noise in this image :D
I found out that you can spam the shoot ball button and all mayhem is awaken.
It was a nice experience which played with the theme differently. I had fun with it for a while. But have to say that I was in the end hoping that when presing the arrow it would take me somewhere else to actually be able to do something myself, maybe control the ball in a world that would make sounds/etc when hitting something.
