Hello everyone

I'm looking for an old pc game. I remember playing this game in 2006 or somewhere around then, although it could have been released earlier. It was a 3D marble game where you had to get the marble to the end of the level. I think in some later levels there were several colored walls you couldn't pass through until you found a crystal (or switch) of the same color to turn it off. I don't remember too much else. Any help would be appreciated
