I'm making a mining/building game in java using slick2D and I want to make it so you can only see a few blocks in any direction while you are underground. The best example I could find of what I want to do is the game miner dig deep.

enter image description here

One way I thought of doing it would be to have a large image and just draw transparent areas on it where you need to be able too see but even if that would be an efficient method I wouldn't be sure how to do that.
