Well, what internet browser do you use? If you use Google chrome, then don't use it. The games on Lego.com are very slow on that. If you use Internet explorer8, then you may find it easier to move the vehicle. It worked for me.

Firefox3.5.3. and it hates flash.
EDIT.. URAW, the instructions in the game saw destructoid!!
Because it IS a destructoid?
BTW your game was not all that hard!
It is hard, at least for me. And the star does not throw you off, it helps... a lot. That 15 extra really helps.
To clarify, it is a Destructoid, and is updated like with the LU Concert Module.
