Low scoring reviews are correct, the game is entertaining at first but the rapid increase in waiting times spoils any fun. Also many of these 5 star reviews seem too convenient, and they are also the only ones the devs reply to, hmmm. A game is not enjoyable if you only check it a few times a day to watch a couple of ads, just to then be bombarded with 'limited time offers' in the range of 10-20 pounds. Ridiculous - double that and I could buy a full game that would entertain for hours.
