Mari0 (pronounced "mari-zero" or "mari-oh") is a 2012 side-scrolling platform video game developed by German^[1] indie developer Maurice Guégan with creative input from Sašo Smolej and released onto their website Stabyourself.net. It combines gameplay elements from Nintendo's Super Mario series and Valve's Portal series. The game features Mario armed with a "portal gun", the main game mechanic in the Portal series, allowing him to create two inter-spatial portals on 2-dimensional surfaces which can transport himself, enemies and other objects through them. It was made with the LÖVE game framework.

Development began in 2011 as a direct port of the original Super Mario Bros. with no clear gimmick in mind. The pair's first idea was to implement a four-player multiplayer system similar to the one seen in New Super Mario Bros. Wii – however, after they viewed a Dorkly video entitled Mario With A Portal Gun, they settled on the idea of including a portal gun and other elements from the Portal series. The game quickly gained traction through online blogs and news sites, and has been downloaded nearly 1.6 million times. It was well-received by critics for its creativity and simplistic concept. An update to the game titled Mari0: Special Edition was planned for release at an unknown date, however it was cancelled in 2015 following technical constraints.
