There was(is) a Limbo-related audio contest going on (https://www.audiokinetic.com/limbo-redux-contest/
). In it composers and sound engineers could manipulate sounds in Limbo to suite their vision.
So I took the first level, included in Demo (up to the spider encounter) and tried to compose music for it:http://steamcommunity.com/sharedfiles/filedetails/?id=224307931
The music I've created works like this: multiple layers of consonant soundscapes were composed and arranged within the map. The final mix is then determined by the player - if he stays idle in some places, music can get intensified, if he moves to the darker regions it will get murkier, if he comes to a well lit area - music will get gentle.
I've tried to make it into a constant flow maintaining the sense of obscurity and threatenig stillness magic that this game has throughout its entirety.
Hope you would enjoy this piece. While this music is a little bit interactive, it might be more interesting to run around the level on your own, so I've uplaoded a demo with music added here:https://dl.dropboxusercontent.com/u/60416939/Limbo%20%28Demo%20with%20Waterplea%20music%29.zip
It's a free demo with a link to purchase game, so I'm sure it should be fine to post it.
