Fun, but buggy and problematic

This game is fun, but somewhat unplayable. My first game crashed after a few minutes of playing. When I reset the app, the game didn’t save and I had to start a new puzzle.

My second game went fine, but I had to go to the home screen to check the time (without fully closing the sudoku app). When I came back to the app, I had to start a new game again. I wish it would auto save where you last were before the app closes.
