In slang, "L7" is often used to describe someone as a "square," meaning conventional or uncool. When applied to a square map in a game, calling both sides "L7" could be a playful way of referring to the map itself as "square-shaped." It emphasizes the symmetry of the map, with all sides being equal, and ties into the slang's connotation of squareness. This could also imply a straightforward or basic design, aligning with the idea of someone playing the game "just to play," without overcomplicating their approach.
