Mari0 2 (also known as Mari3) is a new sequel to Mari0 based on Super Mario Bros. 3. It is currently in progress and very early in development; you can follow the game's development on the official Twitch page. At this time, any sort of release has yet to be confirmed.

Description on Twitch Edit

Mari0 2? Edit

Yes. Kinda.

It's a rewrite I started and then I made it not bad so now it supports angled portals in arbitrary positions, runs better, and other stuff.

Planned featuresEdit

As the game is very early in development, everything in this section is subject to change without notice. Proceed with caution.

  • All elements from Super Mario Bros. 3 will be implemented.[1]
  • Tiles can now have slopes and other free-form polygons for their collision data.
  • Portals have been entirely re-written and are no longer bound to tiles; they can be placed anywhere, including slopes. Portals can even rotate freely, although this may not be used at release.
  • The editor has received several substantial improvements over the first game, with new tools including selection (rectangle and magic wand), copy and paste, fill bucket, zooming/resizing the window, multiple tilesets, stamps (groups of tiles), layers, and more.
  • Custom enemies will be expanded from Mari0: SE into a more powerful Actor system.
  • Animations will also return, powering more of the game's events and transitions such as end-of-level events.
  • Mari0 2 will not be backwards compatible with previous releases - it is an entirely new game.



Origins Edit

Mari0 2 began as a project to port the game for TurtleP's Love Potion, which is a port of Löve to 3DS homebrew. Although Turtle had previously attempted a 3DS port, it was was unsuccessful. In September 2017, Maurice started rewriting some of Mari0's 5-year-old code to be more optimized, and to run on 3DS. Since then, he has posted regular updates on the Discord server.

SMB3 additions Edit

On October 4th, 2017, Maurice reworked portals with the ability to be sloped. He commented that he should just make the rewrite based off SMB3 instead at that point, and later requested sprites of Mario with a portal gun in the SMB3 style. The next day, Maurice streamed "Secret Mari0 2 development", attempting to code pixel-based physics into the game.

On December 22nd, 2017, Maurice stated that he removed all 3DS-related code, since Love Potion was not yet feature-rich enough to support it.

"Demo" release Edit

Main article: Tacogame

On December 28th, 2017, Maurice released a "demo version of the game" (actually just a joke).


  • Despite all other nicknames and inspirations containing the number 3, the official title will be Mari0 2 to keep consistency with the Mari0 series chronology.
  • The game started as a 3DS demo, but it is no longer considered a target release platform.
