I have been working on a hard level for several hours today. When I've used up all of my moves, and it asks me if I want to buy extra moves to complete the game, it has said up to 30 extra moves. I did not buy them. I stopped playing for an hour to make dinner, came back to play and now it is back down to five and will not move. Can you figure out what happened? I need a lot more than five moves to be able to finish this game!
