Well, I remember, but it is really a couple of years ago, maybe 4 years or so. I am not so interested to climb the spire because I really do not know what to do with the diamonds I earn.
... which is a problem currently afflicting me on Live, as it happens - because I don't and won't buy Premium Expansions, nor yet will I use Premuim Currency to 'accelerate' anything at all, in any mobile game, ever. No need to encourage them to slow us down, is my standard viewpoint there...!
I also have 19 Standard Expansions in Inventory, and climbing... thanks so much, 2020 Formula, for that, and more PITA stuff, too...
