Super Mario Maker 2

Super Mario Maker 2 is a 2D platforming and level-editing game for the Nintendo Switch and the sequel to the 2015 Wii U title Super Mario Maker. The game expands on its predecessor with new features such as a level style based on Super Mario 3D World, which incorporates some gameplay aspects from the 3D platformer, including the Super Bell power-up; new level themes, such as desert, snow, sky, and forest; further terrain options such as slopes; and a nighttime feature, which alters many course elements. In addition to Mario, such characters as Luigi, Toad, and Toadette are playable in both single-player and in Network Play, a multiplayer mode which allows the player to compete against or co-operate alongside three random players online. An offline, single-player Story Mode is also featured in the game, which contains over 100 pre-installed courses made by Nintendo. Super Mario Maker 2 was released worldwide on June 28, 2019.

A Nintendo Switch Online membership is required to share, download, and play courses online.

Gameplay
As in Super Mario Maker, along with the main contents of the level, each level is set with a style, theme, and time limit. The starting platform is no longer visibly separated from any ground tiles placed beside it, which are instead merged into the platform. A new mechanic known as Custom Scroll is introduced, which allows the player to set a level to auto-scroll, as well as the directions at which to scroll, which can be changed up to 10 times per area. In forest-themed levels, a body of water can be added and/or set to rise and fall at a predetermined speed. In castle levels and nighttime forest levels, the lava and poison respectively can also be set the same function. The player also has the option to add Clear Conditions to their level, such as collecting a certain amount of coins or reaching the goal as Super Mario. Vertically scrolling sub-areas can also be created.

Enemies that have alternate forms (such as Piranha Plants) can now have those forms selected by tapping the enemy to open up a menu, rather than shaking it. Additionally, that menu also includes the options to insert/remove a Super Mushroom (although Super Mushrooms can be added by dragging them onto enemies like in the original Super Mario Maker), wings, and a parachute.

In editing mode, the basic functions from Super Mario Maker return, including Mr. Eraser and Undodog, and the player can quickly switch between playing and editing by pressing. As a new feature, the player can zoom in or out during editing mode to gain a different view of the level, the latter performed by clicking one of the analog sticks. If the player switches to Super Mario 3D World style, everything that has been placed on the editing screen will be erased, due to the style's course elements being vastly different from those of the other styles. Courses can now be edited cooperatively.

Story Mode
In Story Mode, after Mario, Toadette (referred to as "Chief" in this mode), and several other Toads have finished building Princess Peach's castle, Undodog accidentally steps on a button that causes a Reset Rocket to erase the whole castle. As such, Mario needs to collect coins to rebuild it. To earn coins, the player can play through over 100 official courses produced by Nintendo in the form of "jobs" given by the Taskmaster. After clearing a course, Mario keeps the coins he collected in the course and is also awarded a coin payment. Some of the levels also feature Toads that need to be rescued. Other NPCs including Mr. Eraser and Undodog can also assign jobs for Mario. The main hub is set in and around Peach's castle in the Super Mario 3D World style, and the player can explore more parts of the castle as they progress through the mode. Luigi, Toad, and Toadette are not playable in Story Mode.

Course World
Course World, the online hub in which players can access levels created and uploaded by other players, returns from Super Mario Maker. In addition to being able to browse popular courses, searching by course ID, and download courses, players can now search courses by specific parameters such as style, theme, difficulty, and region, similar to the search function on the website. Courses can also be searched by tags that have been applied to them, such as "Puzzle-solving" and "Autoscroll". Feedback can be given to courses in the form of text, drawings, or one of 12 Mario-themed stamps, and players can choose to vote on courses positively or negatively by selecting the "I like it!" or "Boo!" buttons respectively. As in the first Super Mario Maker, the clear rate and world record are recorded for every course.

Each player on Course World is represented by a Mii and has their own Maker profile, which displays their medals, Maker points, and Versus Rating. Maker points are earned if players clear courses and react with "I like it!" for each one. However, maker points can be lost if players fail to clear a course, and/or don't leave behind any kind of positive reaction; this includes giving the course a "Boo!".

The Versus Rating represents the player's rank in Multiplayer Versus matches based on their win-loss ratio; if the player wins a match, they earn points, and move up a rank if enough points are earned. The player can also dress up their Mii with various outfits and hats obtained by completing certain objectives in the game.

Network Play
Network Play allows the player to cooperate with three other players online to complete courses in Multiplayer Co-op, or compete against them to clear the course first in Multiplayer Versus. Each player is assigned to one of four characters: Mario, Luigi, Toad, or Toadette. The player can also connect locally to other players who own the game, though the players' Versus Ratings are not affected in this mode.

Endless Challenge
Similar to the 100 Mario Challenge in the first Super Mario Maker, Endless Challenge involves the player completing as many random courses based on their preferred difficulty as possible. Players that achieve a significantly high score are ranked on the leaderboards. Courses have to be played at least once before they can appear in this game mode.

Yamamura's Dojo


In Yamamura's Dojo, the player can view "Maker Lessons," a series of tutorials in which Yamamura teaches a new character, Nina, various course design techniques. Maker Lessons are categorized into three levels: beginner, intermediate, and advanced. The player can also view the controls for each game style, under the option "Mario's Moves."

Course elements
Instead of displaying every element on a single screen as in Super Mario Maker, at the top-right corner of the screen in editing mode, there is a magnifying glass which, when selected, allows the player to search for course elements by category. Each category's elements are organized into one or more wheels, with the elements as the sectors. The top of the screen contains the most recently used elements, but elements can be pinned.

Elements formatted in bold are new to Super Mario Maker 2.

Styles
The game styles are separated into two categories; game styles that feature their own unique elements that are incompatible with other styles are placed in "Extra Game Styles".
 * Super Mario Bros.
 * Super Mario Bros. 3
 * Super Mario World
 * New Super Mario Bros. U
 * Super Mario 3D World

Themes
{|class="wikitable" style="margin:auto; width:85%; text-align:center"

Terrain
The terrain category is represented by a Brick Block icon and colored blue.

Items
The item category is represented by a Coin icon and colored pink.

Enemies
The enemy category is represented by a Goomba icon and colored green.

Gizmos
The gizmos category is represented by a key icon and colored yellow.

Other
These course elements are not available in Course Maker.

Sounds
Sounds reappear along with several new ones, accessed by tapping the Soundfrog icon. As with course elements, they are divided into several wheels. Additionally, the secondary forms of sounds are now separated from their base counterpart. However, the ability to record sounds was removed due to the Nintendo Switch's lack of a microphone.

Clear conditions
Clear conditions are a new feature that requires the player to fulfill a given condition by the end of the level in order to make the goal appear. Similar to the conditions in Challenge Mode from New Super Mario Bros. U, some clear conditions are incomplete at the start of a level and must be completed, while others are complete at the start but can be failed before reaching the goal. Failing a clear condition does not cause the player character to lose a life immediately, but they will be unable to interact with the goal without restarting the level.

Each level can have one or no clear condition. Levels with Checkpoint Flags cannot use clear conditions.

Parts
In Multiplayer Versus, players cannot see their progress on meeting the said clear condition until someone completes it. The first player to complete the clear condition can interact with the goal, but other players can steal it by stomping on the player with the goal mark. The player also loses the goal mark upon losing a life, allowing others to steal it.

Other
These clear conditions are not available in Course Maker.

Original games
The following is a list of differences from the level styles' original games not present in the first Super Mario Maker.

 * Sky-themed levels now have new music based on the overworld theme arranged by Koji Kondo, unlike in the original game where the original overworld music is used instead.

 * ON/OFF Switches replace Switch Blocks from the original game functionally.

 * The flagpole does not turn gold when the player touches the top of it. Additionally, it now provides an extra life rather than 10,000 points, akin to the other game styles and Super Mario 3D Land.
 * Fire Toad now has a blue cap instead of yellow. This is to be consistent with New Super Mario Bros. U.
 * The snow theme, which appears to be based on Snowball Park, takes place during the day, instead of the night like in the original level.

 * One-Way Walls are now in the same group as the Arrow Sign.
 * Unchained Chomps, Angry Wigglers, Lit Bob-ombs, Bull's-Eye Blasters, Red Cannons, and Fast Lava Lifts now have their own "singing parts" in the edit screen, rather than the same as their original counterparts.

 * Normal-sized shells now deal more damage to Bowser.
 * Instead of big Yoshi Eggs being green and hatching into two Yoshis that run around in panic, they turn red and hatch into a single red Yoshi that does not run away.

 * Big characters cannot break blocks by running into them. Also, taking damage now degrades them to Super form, rather than Small form.
 * As Mystery Mushrooms have been removed, Big Mushrooms now replace Super Leaves, Cape Feathers, Propeller Mushrooms and Super Bells from other game styles in the parts menu. This means the player can no longer place Big Mushrooms outside of the Super Mario Bros. style.

Debut trailer

 * The icons for several of the Super Mario 3D World course elements used different icons than the final game as placeholders.
 * The following used their icon from the New Super Mario Bros. U style:
 * Pipes
 * ? Blocks
 * Hidden Blocks
 * Ice Blocks
 * Semisolid Platforms
 * Koopa Troopas
 * Cheep Cheeps
 * Hammer Bros.
 * The following used artwork from the Super Mario 3D World Prima guide:
 * Clear Pipes
 * Brick Blocks
 * Rock Blocks
 * Donut Blocks
 * Goombas
 * Porcupuffers
 * Piranha Plants
 * Fire Piranha Plants
 * Thwomps
 * Piranha Creepers
 * Stingbies
 * Hop-Chops
 * Trampolines
 * The following have a different icon in general than in the final game.
 * Cloud Blocks
 * Pink Coins
 * 10-Coins
 * Spinies
 * The early icon of the 10-Coin was simply a standard coin with the number 10 on it.
 * The Goomba icon in the Super Mario 3D World style used artwork of a Mini Goomba instead of a normal one.
 * When the underground theme was shown in the Super Mario 3D World style, the Block icon was a Brick Block rather than the Crystal Block in the final game.
 * There were only three enemy wheels instead of four in the Super Mario 3D World style. Additionally, Porcupuffers and Bullies were placed in the first and second wheel respectively instead of the fourth.
 * When Custom Scroll was shown off, the icon used for the scrolling points was more simplistic, consisting of a silhouette of a realistic-looking parrot instead of a more cartoonish one with a visible facial features.
 * The Twister in the Super Mario World style had a different appearance than in the final game, somewhat resembling a Foo.

Super Mario Maker 2 Direct

 * The underground theme in the Super Mario Bros. 3 style used the brown palette for ground tiles in the day version.
 * When showing off the feature to use the ON/OFF Switch with Tracks, the Twister in the New Super Mario Bros. U style had a different appearance than in the final game, resembling a Foo, like in the debut trailer. However, since the final version's design also appears in the New Super Mario Bros. U style, this was most likely intended to be some sort of alternate form.

Staff
Yosuke Oshino, who directed the original game and its Nintendo 3DS port, returned as the director to the game. New music for the game was composed by sound director Koji Kondo, and additional soundtracks were worked by Atsuko Asahi, Toru Minegishi, and Sayako Doi. Takashi Tezuka and Hiroyuki Kimura are continuing producers of the game.

References to other games

 * Mario Bros.: Fire Luigi in the Super Mario Bros. style resembles his appearance in Mario Bros. for the Atari 2600, as well as the game's flyer ad. Mario's walking sound effect as well as other sound effects from this game can be heard during loading screens. Also, the four sub-areas in the story mode level Underground Coin Collecting are modeled after Mario Bros. stages.
 * Super Mario Bros.: The first game style is based on this game. Some blocks that prevent Mario from going forward or through pipes in Story Mode's main area use a 3D version of this game's ground sprite. In Story Mode, Yellow Toad makes statues of 3D versions of the Goomba, Koopa Troopa and Cheep Cheep's sprites from this game. The story mode level Super Mario Bros. W1-1? by Princess Peach is a remix of the first level from this game.
 * VS. Super Mario Bros.: A portion of the newly arranged music for the sky theme in the Super Mario Bros. style borrows the "Name Entry" theme from this game. The "Name Entry" theme also returns as the Bonus theme in the Super Mario Bros. style.
 * Super Mario Bros. 2: The door sprites return for the Super Mario Bros. 3 theme.
 * Super Mario Bros. 3: The second game style is based on this game. The P Switch, Boss Fight and Final Boss themes in the Super Mario Bros. theme are from this game.
 * Super Mario Land: The Superball Flower is available as an item in the Super Mario Bros. style. The music that plays while in the Superball form is a remix of the Birabuto Kingdom theme from this game, and the music that plays when completing a level or losing a life in said form comes from this game.
 * Super Mario World: The third game style is based on this game. The music heard in the map of the Endless Challenge at the Easy, Normal, and Expert difficulties are arrangements of Yoshi's Island's map theme from this game, while Super Expert's and the bassline of Expert's are arrangements of Valley of Bowser's map theme. The music that plays elsewhere in Course World is an arrangement of the Special World's map theme.
 * Super Mario Kart: The "Mario Circuit" theme is featured as a sound effect under the "Musical" category, represented by the Super Famicom logo.
