Oh, it's me. Black Fell is a little* different to the other pieces in this series as it requires you to 'play' it yourself through the game interface –  though you can just choose to stand still, if you want. The path you take and the sounds you follow will create a piece that is uniquely yours. There is no right or wrong way to do it, and no goal to achieve: just explore and listen. If you play it multiple times you should be rewarded with a richer understanding of both the narrative and of how you influence what you hear by your movements. It won't work on a mobile device unfortunately, but I promise it's worth dusting off your laptop/desktop for.
