Super Mario Maker's Facebook hackathon is now over, the winners have been declared, it is... The Facebook R&D Division, they'll get the chance to add their team's level to the game after the game's launch. Personally, I believe this is fantastic for the game, because having a unique level designed by Facebook employees adds a new fun to a game that already looked appealing to many, including myself. Hopefully they'll be releasing more details (like a video) of the hackathon Facebook event as we approach September 13th, 1985 (the anniversary of SMB)
Game on and Keep it Rehl!
