The player’s journey will go through many different worlds, each of which has a boss at the last level. The overworld allows the player to control the overhead view, thus moving between different kingdoms and levels with lines while the level playfield is where players experience levels. Also, players will control the character through two screens, that is, overworld and level playfield. Along the way, players will pick up various items that can enhance Mario & Luigi, and their skills will depend on the type of item the player has picked up.
This game is developed in the style of a side-scrolling 2D platform, and players will control the couple to overcome all challenges with basic actions. Super Mario Bros 3 has gameplay similar to previous games, and it introduces many new features, along with specialized skills for Mario and Luigi.
