LOVE the Jigsaws but...Problem fixed!!!! – Just Sudoku - Puzzle Game Review

The prompt response of this developer is rare and greatly appreciated! I wrote a review mentioning the pencil marks could not be seen in the darker jigsaw puzzles. The developer responded immediately and today, less than a week later, the game updated and the problem was fixed?! This is the BEST sudoku app I have tried and the only one to offer the challenging jigsaw puzzles!
