Love it but Im having problems

I love this game and its very addicting. Id definitely give it five stars but somethings going on with it. I finish the first two levels then it makes me do the 2nd level AGAIN and it wont let me continue and if I leave the game and come back it goes back to the 1st level instead. Please fix this, if you did this would probably be my new favorite game.
