Initially a great game, echo other players comments, once you get to a certain level, impossible to progress unless you spend money or watch endless adverts. Way too many updates and with every update the goal posts are moved. Used to be able to play offline, now you have to be online. Now can't play at all as getting a constant message saying I am not connected to the internet but I am. Very frustrating. If I was to spend real money, why is everything priced in $, I am in the UK?
