So I had a bit of time this Sunday and was messing with the images that I use to render the scene. I had created sprite sheets to store all the images in, but it was getting increasingly annoying to add new tiles to the sheets. So I decided to split them up in single images. As I don't expect to have to many images in my little game it should not be a problem.
Refactoring a very important and deeply rooted function of a game is quite a big task. But well worth the effort when it's done. Might be a good time to separate the slick images from the game so that I can replace slick later if it proves not to live up to my expectations.
