I'm well past level 14,000 and it seems like my playing ability has tanked lately. For awhile, I was winning every race and cranking out levels at an amazing rate. I truly believed I'd get to a point where I caught up with the latest available level. I no longer believe this can ever happen.
At some point, I reached a point where even the basic levels were so hard that I needed gold bars to get through them. I expect to be fully out of gold bars within a couple of weeks and then I'll have to stop playing. Has anyone else experienced this?
