Lighting effect

I was inspired by the artwork in a Indie game called Legend of Dungeons. They had REALLY good pixel art and used shadows and light. I am trying to make a game where you're using a flashlight and I wanted the light to guide your path through the shadows kind of like in the Ghost Shooter game ,but I couldn't find any help on the tutorials. Any ideas?

Check out the Blend Modes and Effects manual page. And take a look at the examples that come with C2.

You can make a layer that is black, but have round shapes (light) that poke a hole through the black layer, or they can use an Effect to become Additive
