The rating used to be 5 but after I updated the app today it will not load. It boots me and says the app has stopped working. I sent feedback when it gave me the option but nothing has been done about it. I am not going to keep it on my phone if it continues to do this. So please fix it!! Edit: thank you for fixing the issue! Now I gave it a 3 because I make energy and everything.but because it takes so much energy to clear one dirt pile I can only play for a couple mins!
