The only problem I have with this game is that I can't take it with me. I have it on my tablet but can't sinc it with my phone. This causes me to not finish some of the islands. Also, if I don't buy, it takes forever to get more energy to clear the land and get those resources. So I tend to play for a short time then go somewhere else and if I remember and/or have time, I will go back and use the little big of energy that accumulated. Overall, it is a good game though. I enjoy the different story lines and this to do.
