New Nitrome game worth your consideration. They really are a consistently innovative online game producer, and that is pretty rare so the least you can do is give them a click. Otherwise they could very well get swallowed up by the thousands of clone games being wheeled out by unimaginative bandwagon-jumpers. Anyway! Play Knuckle Heads.
Also, a nifty little physics based game that I've been enjoying. Use your little car thing to push the ball thing towards the stick thing. Oh, and make your way around the myriad obstacles. It's called SteerWheels and you should play it.
