Fun, but requires purchases to complete – Hollow Words Review

I liked this game a lot. Some of the puzzles were challenging, many were easy. I dislike that to unlock later levels you cannot win enough coins via game play and must purchase more. I'd happily play all the way through it, but not if I have to make an in-app purchase to do it. Especially since it already displays an ad at startup.
