One of the biggest issues with maps like these is memory usage. It can be easily wasted on something unnecessary or even invisible to the player. Optimization is something that is important to keep on top of as you go along. This means things like making sure objects that the player won’t see aren’t rendered and any objects that aren’t part of the vital layout of the level are turned into entities. As shown in the image below when a solid becomes an entity the game engine does not calculate the environment around the object and so save much space and much time rendering the level especially if it’s a particularly complicated object like a sphere.
