Terrific game, but .... This is a great summer review game. The kids love it, but there doesn't seem to be a way to reset it once a child has beaten it so another child can play. It would also be nice if there was a way to have more than one user so each child could save his or her own progress.
Great game Since a recent update to adress sensitivity issues on small screens this game is very solid. My 7 year old enjoys it alot. Customer service was top notch as well. I highly recommend!

-- Added reset function to reset all progress in case of multiple children wanting to use the game to play their own progress
