Super Mario Bros.: The Lost Worlds is a retro-inspired take on the Super Mario Bros. franchise similar in tone to the original Super Mario Bros. and Super Mario Bros.: The Lost Levels/Super Mario Bros. 2. It uses the engine from Super Mario Maker Phi. It was developed for The V² by Toroko. It was released as a digital only title and lacks a true boxart because of that.

The game's concept revolves around a "missing adventure" that Princess Fusee uncovers, with some of the missing chunks replaced with stuff that Fusee thinks would have made a good retroactive fit. The game's prologue, World 1, centers around Mario and Luigi getting back to the Mushroom Kingdom. The game also features Peach as a playable character, multiple level paths for some of the worlds, new kinds of level layouts, new enemies and a new power-up.

Plot

The plot was only described in the digital manual for the game.

Princess Fusee was doing some house cleaning in the Time Citadel when she encountered a entire missing chunk of Mario's history, adventures that were lost to every one in the Mushroom Kingdom. Fusee decided to restore this chunk of history but had to recreate parts herself using cloned portions of Mario's past. Not knowing anything about these portions, Fusee had to get a little creative...

Mario returned to Brooklyn after the events of Super Mario Bros. with Luigi, but yet yearned to be back in the Mushroom Kingdom, where he felt he had truly belonged. Although Peach had not been kidnapped, Bowser's forces were attempting to seize power throughout the entire Mushroom Kingdom, looking for the Red Artifacts. Mario, along with Luigi and Peach headed out to stop Bowser.

Gameplay

Super Mario Bros.: The Lost Worlds is split into eight brand new worlds, each which have four levels. Mario, Luigi, and Peach have to get to the end of each stage by either going down a flagpole, defeating a boss, or collecting a Horostar or Red Artifact.

The game has three modes upon starting it up: Mario Game, Luigi Game, or Peach Game. These modes are explained in more detail in the character section. There is no two player mode, continuing it's absence from Super Mario Bros.: The Lost Levels.

The game is a more open-ended experience, with some levels having multiple ways to end them. Additionally, the game allowed players to go back to levels they already completed through the use of reverse Warp Zones, which have a actual purpose other than to punish the player for exploring. The game has multiple secret paths that contain extra levels and unlockables. The game of course, has Warp Pipes that allow the player to skip multiple worlds if they please, but the player will have to play through the game in a multitude of ways in order to see everything this game has to offer.

Characters

There are three playable characters in Super Mario Bros.: The Lost Worlds; Mario, Luigi, and Peach. Both Mario and Luigi start the game the same way, although Peach has actually somewhat different levels when she begins the game. From World 2 onwards, they have the same exact levels.

Luigi jumps higher than his brother Mario but is slippery and hard to control. He acts about the same as he did in Super Mario Bros.: The Lost Levels.
NESPeachPhi

Peach

Peach starts off much slower than either of the Mario Bros but has floaty jumps, allowing for more air time and farther overall reach than both Mario and Luigi.

Worlds

Unique to a Mario Game, the first world of this game actually takes place within the sewers and a construction site.

World 8: Bowser's Bastille

World 8 is Bowser's Bastille, and easily the greatest challenge for the player. The levels include multiple boss-level threats with Blue and Red Bowsers, some levels even ending with Fake Bowser boss battles. The only new enemy is the Fire Bar.

Course Information Level Exits(s)
World 8-1 A castle themed stage not unlike what we've seen in the Mario franchise before, except the lava is on the ceiling and bottom of the screen. Lava Bubbles and Fire Bars are spread across the entire level with Sledge Bros and Pink Shell Koopas acting as the primary enemies. There is a fight with a Fake Bowser at the end, which reveals itself to be a Hopfish. Defeat Fake Bowser

RedMaskSMBTLW Secret Exit: Collecting the Red Mask.

World 8-4 (Normal) This stage is a castle with a door maze, leading into several rooms where enemies need to be defeated. There are six rooms, five of which have a different enemy type inside (Goomba, Koopa, Cheep Cheep, Hammer Bro, and Sledge Bro). The last door leads to a fight with a Red Bowser, then past that a Blue Bowser, and then finally a real Bowser who has locked off the axe with a pile of blocks. The player must either wait for him to jump down three times to gain access to the axe or take him out with fireballs. At the end, a Toad will greet the player and note how many Red Artifacts they have collected, stating that another adventure awaits when they obtain all four. Defeat Bowser.
World 8-4 (Secret Route) When the player has collected all the Red Artifacts, a different 8-4 pops up instead. This 8-4 is a fairly normal castle level, except with a bunch of cherry blossom trees in the foreground and the background. The route is filled with Fire Bars and Lava Bubbles from the floor and ceiling, making jumps super tricky at times. The player will then run through a Red Bowser, then a Blue Bowser, before taking on Bowser. The fight is identical to the Normal 8-4, but when Bowser is defeated there is no lava for him to fall into, but rather a pit with a cherry blossom tree in it. A cutscene shows him falling to his death, and then the player talking with a Toad before Bowser reappears as Blossom Bowser. Blossom Bowser attacks with Blossom Balls that the player needs to jump onto to redirect, and after three redirection hits Blossom Bowser goes into another stage where he can guard off attacks and attack with Cherry Blossom trees. The player must hit him with a Pink Koopa Shell three times when he reveals his weak spot, and then the game will finally end... or will it? Defeat Blossom Bowser.

World A

When the player defeats Blossom Bowser, they open up the secret letter worlds. World A, World B, World C, and World D include new levels but no new mechanics or enemies. What is unique about these levels is that they contain Horostars instead of a traditional flagpole. Horostars appear in the player's HUD next to coins now. The player can also skip to World A when they begin a new game right from the start, as the player will now spawn on top of a black pipe with the letter A on it.

When the player begins World A, Fusee gives a briefing to the player about needing to find the Horostars to reconnect the adventure to the timeline. The player then must collect all the Horostars.

Course Information Level Exits(s)
