I play on a Kindle HD. I started playing before the Christmas update on a KindleFire. I have crashed four times, twice losing everything and starting over at level one. I am currently recovering from my lastest crash where I lost all my inventory and collections items. I am dreading the current update for kindles as I fear another crash. This last one was the easiest as all my friends from this site caught me back up in less than two weeks. I am currently multiplying while waiting the update. I can't time travel on my device. I like my pictures to be charged and I like charging everyone's pictures to see how they are progressing in the game. I hate pieces mode and when the pictures refuse to change when you are trying to complete a task.
