I second all the other comments about it letting you play for a while, but ultimately is unbeatable without many micro-payments and certainly watching a lot of ads along the way. I'm sure the developer is going to ask what we can change to make it better. So here you go. I would be happy with a version that lets one purchase once up front and have the satisfaction of realistically completing the game. That is a way to remove ads and all required in-app purchases to reach a satisfying ending.
