Good concept, little laggy, and the sound effects were so annoying! Please change the sound of the car driving so it doesn't loop every 10 seconds =o
I loved it, and I had quite a good run with my friend (even though I sucked hehe). Only thing I would say is that the graphics (wordart) as the introduction wern't to my taste. That's it really, For a simple multiplayer flash game it pretty much rocks :D.
