|Mari0, Mario has been given a Portal gun, and he can navigate the levels by making good use of it. It’s available for Windows, OSX and Linux, and you control it using a mouse and the ASDW keys on your keyboard, while jumping is assigned to the spacebar. The game looks cool!
"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!"
