They have not outright said so but I think the developers are done with this game.
The last update was the twiggy lake link into bushwhacker two, hint hint, kind of signifying the end.
But wait, I think the update of the 8 individual squares all over the world came out after that. In either case that was almost a year ago.
Even some of their repeated yearly holiday events have been late, kind of like they forget to do them even though there has been nothing new since the schools out event last year. That should be coming up soon and I bet it will have nothing new...
