Best "create-a-car" physics game I ever played. At first could be hard for some people, but is really great when you get the think (I have included various world records! :))
You don't have imagination, "metalmaster"? There is a story included, and good one, with a very good ambientation. Is the players who fill the gaps. And there IS speed control (by the obstacles)
I like the idea of travelling along different planets, thougth I don't like specially the graphs of this own, the contrast is too much brigth. Pseudo, don't care about the criying babies what don't take along with difficulty, and even don't played the first game (Necesary to play this one)
