I really enjoyed this game and was getting pretty far into it but its my second time playing it. The first time I hadnt signed it up with the game center and though some games give the option to link it to game center and start anew or continue with the original data when signing into game center- it didnt and I lost everything. There is no alternative to signing in besides the memory or game center. This second time, there was some server update and when trying to continue from where I left off- it continuously kept taking me to sign into my game center though I have it logged off and started this second game without game center. I am unable to play it. This game is inconvenient because you cant even play it and there is often lagging that is sometimes associated to the network connected to (wifi) but other times not. It will also glitch occasionally. Besides this, it provides lots of options and fun. You dont have to invest money into the game to get far very quickly. Its also convenient for people who dont want to play a game that requires 100% of their concentration and for people who dont want to play for hours on one game to get somewhere. This is where the "idle" part comes in because the game generally continues though youre not playing it and you level up and earn rewards. Sometimes though itll stop in the middle of this and not continue- perhaps because of a glitch? I dont so much mind the random lagging or bugs which are fixed with updates but what bothers me is that there isnt an alternative way to signing into the game so its extremely easy to lose all of your progress with no way of recovering it. Although there is information available in the guides there should be an area where questions can be asked and answered by others and staff because Ive often found that the answers provided leave out certain terms or topics or arent thorough/detailed enough.
