Looking for a fun online racing game like Nitrome's Flipƨide

What I’ve been playing is this: http://www.nitrome.com/games/flipside

It actually plays kinda like the oldschool sonic games. Now that I’ve finished Flipƨide for 400 times or so, I’m looking for a new online racer. Preferably 2d, and topdown would also be good. Does the dope have any recommendations?
