Have you ever wondered what if would be like to play Super Mario bros with Mario possessing a Portal gun? Well now you don’t have to wonder anymore! A two-man studio called Stabyourself has created an open source game that has merged the two games, giving Mario a Portal gun!

“A complete from scratch recreation of Super Mario Bros. with a focus on perfectly imitating the feel the 1985 classic gave us. Then give Mario a portal gun, add puzzle game mechanics from Portal and there you go. And if that wasn’t crazy enough, play 4-player coop, with everyone having their own Portal gun!”

Here’s a teaser trailer for the game:

And if you want to play it, you can download it here for all platforms including OSX! (I love it when they do not exclude us Mac users) ^^

The creators also have some other great games on their page, like “Not Tetris 2“, which is a Tetris successor with no boundaries. Quite interesting, now I know what I will spend my afternoon playing!
