Was good till it became unplayable due to crashes

Fun game. Played it for a while, and let it take some money from me. First it started disconnecting from the server a few times during playing, once in a while. But now it just crashes as soon as I try to open it, and can no longer get in to the game. Had the exact same experience with this same game a while back. Gave it another chance thinking they fixed it, but here we are again. If they would make it stable I would give it 3 or 4 stars since the in app purchases are annoying.
