I love this app, I've always loved these kinds of puzzles. Why not 5 stars then? The recent update that makes a popup of "% people who finished this puzzle" that pops up on every. Single. Puzzle. Make that go away or add an option up toggle it on or off (if there are any people out there who actually want that on there) and I'll happily add more stars back. But right now? This addition seriously impedes my enjoyment of this game
