If you never saw the awesome side-scrolling experiment that was the original Super Mario Bros. with a Portal gun, you're missing out.

Thankfully the author of said experiment has decided to actually go ahead and create a game around his curiosity which we're assuming will be shut-down within minutes of being released, so are giving you a heads-up early in a chance that you just *might* be able to get your hands on it before Nintendo's lawyers do.

It's ambitious, to say the least, but the team at Stab Yourself are releasing it for free with the source code and are encouraging the community to build and share maps.

So who knows, Mari0 might actually survive release, but either way, we're happy it's even just in development.
