Run n' Roll is an online multiplayer flash game that lets you play chase with people from around the world. Your character runs on his or her own, all you have to do is jump over or roll under objects. You stay ahead by, well, not falling behind. Grab a few fun power-ups to stall your opponent as you race around a giant sphere in the sky.
C'est bizarre. From Paris, France, Yamago.net is a talented bunch of Flash and web folks that serve up games and cartoons, and multiplayer environments. Many of their games are very strange, like the one I've highlighted here: Sick and Famous.
