A New Game - Google Maps Marble Madness

I know nothing about this game other than what appears in the video and the description given by Google on YouTube,

"Coming soon, play your world like never before with a game from the Google Maps team on Google+ Games powered by WebGL."

It looks to me like it is a Marble Madness type game built using Google Maps. That's enough to get me excited. According to the video the game is due to be released in February.
