Mari0 (yes it's a zero at the end of mari0) is a fan game created by Maurice Guégan from Stabyourself.net. It's a mix between "Mario Bros" and "Portal". In this game Mario can shoot portals to teleport things! And you can even create your own levels!
This theme is about a level I made from a mappack not released yet, the 3 heroes on the top are exploring this strange UFO.
I made other mappacks by myself, here is the link to watch the trailer, all the download links are in the video description: https://www.youtube.com/watch?v=Ys-LctVWykA
Enjoy this theme though !
