Why can't we play or repeat older levels? I keep running out of levels as I am presently at level 19,411 and in order to play at all the only option (when open levels are repeatedly completed) is the 'Mastery Level' and those gain absolutely nothing by way of rewards or accomplishments. Also, I used to not consider a level 'complete' until I earned 3 stars. That option too is ruined!
What benefit do the creators of this game get by stripping the fun, motivations, and play from the actual players?
Such an arbitrary move that has fairly ruined the game . . .
