World 3-3 (Super Mario Bros.)

World 3-3 is the third level of World 3 in Super Mario Bros. and the eleventh level overall in said game.

Layout
The player starts on a stretch of land that ends at a platform the player needs to jump onto. On the second platform is a Little Goomba that may fall onto the player if they aren't careful. After the second platform are two lifts that move horizontally, followed by platforms with Koopa Troopas and a ? Block containing a power-up. Afterward is a lift that will fall when the player jumps onto it that can help the player reach a higher path that ends at a scale, standing on one end of the scale will cause that end to fall and the other end to rise and both ends will fall after they reach a certain point. After the scale are three horizontally moving lifts followed by more platforms and a Koopa Paratroopa. Finally, there is a platform with two Koopa Troopas followed by a horizontally moving lift and a scale that can help the player reach the top of the flagpole.
