The creators have added more features, but the adverts are almost non-stop, and there are too many faults, that keep eroding your progress. There's no way I'd pay for some of the features, for example, purchasing gold bars etc, because the game keeps crashing, and deducting the gold bars, and not getting the power ups, or whatever feature you've paid for. The game has multiple faults which are too substantial to warrant paying a fee for.
