I'm trying to make a (flash)light effect for a platform game. I've used the method used in the example file, by creating white circles on a black layer with blending mode set to 'Destination out'.

Now I'd like to exclude the background layer from this effect, the following image shows what I mean.

Is this achievable through blend modes? Could I somehow set a layer to mask the underlying layer like in Photoshop?
Here's the .capx, but it's not that different from the example file.
