You see, the 0 looks like a Portal! (Wow, the stupid font makes the 0 almost indistinguishable from the o)
What started as a pretty awesome idea has now turned into a finished fan-remake of Super Mario Brothers with fully functional Portal-Guns. It takes a lot of getting used to if you want to use the Portals to your actual advantage as opposed to just dicking around with them, but the trailer shows off some nice ideas and I’d say the sky’s the limit here. There is also some other stuff, like a level editor, free DLC etc etc. For Science!
Get it here.
