Multiplayer game where you play as emojis

I remember playing an online desktop game where you were controlling an emoji through some kind of maze in a 2d environment. There were probably several different maps but one I remember looked akin to this neon looking Sonic map, I guess (albeit it might have used warm colors more often). 



If I remember correctly, you could play it without signing up or downloading it. However, without signing up, you could not message people.

I remember playing this game around 2010, albeit I am not 100% sure.

Does anyone else remember this game?
