Just another stacking processes game. This thing produces 20 currency per second. Build 50 of them. Now you can build this other thing that produces 1 million currency per second. And so on and so forth to what end? You'll watch zillions of ads. It's fun for a while but eventually you'll ask, what the hell am I wasting all this time for? It's the same game as many others just reskinned. There's no real gameplay. It addicts you with "just one more" but each one more is anticlimactic.
