If you're asking why are the stars for, each star means that that marble has 2000 for each star. (If 2, 4000, if 3, 6000, and so on until they reach 5) if the stars turn Blue, that means they have 11000 - 12000 points. If the stars go Pink, it means that marble has over 12000 points.
If you don't know how this works, here it is:
The Marbles will try to finish different types of rooms in order to pass, but there is a time limit, so the Marbles will have to finish the course to pass to the next one, else they will be eliminated.
-- Controls --
Press Number keys 1 - 7 to spotlight the rooms. Press 1 for the red room, press 2 for the orange, and so on.
