Well, not quite. It's a bit unlike Centipede. ("Snake"?) The main difference is small, yet significant. You'll be "drawing" a line as you move about, (As in Snake), but the wall you create in your wake will stay there and not follow you. So a lot of the game involves "racing" next to the other player, trying to wall him or her down, make a left turn just in time for it to crash into your wall, and so on.
