Hi all, I'm working on a platform game that doesn't use tiles - I use box2d for collision detection. The idea is to place boxes/spheres that will determine the world collisions, but the question is how to place artworks on top of it? How is it done in games such as Braid or Limbo ? I dont see any tiles repeating, it looks like the whole level is covered with a single image. I suspect using a single big image would be probably slow and memory consuming (the image would have to be like 10000x10000px). I cant think of any clever solution to this.
