World 7-1 (Super Mario Bros.: The Lost Levels)

World 7-1 is the first level of World 7 in Super Mario Bros.: The Lost Levels.

Layout
The player begins next to a grounded and hanging set of pipes with Piranha Plants in them. Past them is a small flight of stairs, where wind will begin blowing as the player jumps up them, with Koopa Troopas at the top. The player must then use the wind to jump cross the large pit and land in an area with four grounded and hanging pipes, with a power-up in a Brick Block above the third pipe. After the pipes are two pools of water that have Cheep Cheeps jumping out of them, with a long platform above with a Bill Blaster and a Brick Block next to a pipe containing a Super Star. After crossing the waters, the wind will stop blowing. If the player jumps off of the Koopa Paratroopas, they can reach a Warp Pipe leading to areas with Coins and a row of various enemies. Otherwise, the player will have to fight two Hammer Bros., which will begin charging at the player once they are on screen. In the Brick Block above the fourth ? Block from the right is a power-up, and there is a Hidden Block with a 1-Up Mushroom on the right end of the row of Brick Blocks. Across a pit is the Warp Pipe the player would exit out of the alternate path, followed by a set of stairs with another Hammer Brother that will charge at the player. After the Hammer Brother are narrow platforms, one of which having a Bill Blaster on it, before the Goal Pole.
