Awesome  but one flaw This app needs to have the """"""""""""""""swipe to delete puzzle"""""""""""""""" function removed. I dont know how many times I've gone to fill a square in the top left  accidentally clicked the back arrow and permanently deleted my current puzzle in one second with a tiny accidental swipe . This is very frustrating. Just keep the """"""""""""""""clean up"""""""""""""""" feature  it does everything I need!""
