World 6-4 (New Super Mario Bros.)

World 6-4 is the fourth level of World 6 in New Super Mario Bros..

Layout
This level has Firebars throughout the level. When the first Firebar appears, Mario should Wall Jump above it to get the first Star Coin. Mario should then come across the thin floors with his back against the wall. To avoid most of the Firebars, Mario should stay down, below the thin floor. Later, Mario must press a ! Switch to create two blocks that let him advance. After the checkpoint, Mario should go left to get the second Star Coin. After the red pipe, the player will be in an area filled with thin floors. Because Mario's jumping is limited, he should only jump when he is close to a moving platform. When the path splits, the player should take the upper path to reach the final Star Coin. After the Warp Pipe, Mario will reach the Flagpole.
