Good game, only get a few levels of game play

Overall a great puzzle app, but what is not obvious is that you only get something like 10 puzzles (less than 20 minutes) in the non-HD version before you have done all of them, then it wants more money for the next set of (10?) levels. Contrast to the #1 app right now, where you get over 140 levels for the same price.
