Very addicting! Its my new solitaire!

Everything with this game is great! Simple, to the point and addictive BUT.....can someone please please put in an UNDO button. Im constantly trying to beat my high score and sometimes the blocks dont always go where I put them so an UNDO button would be PERFECT!!! Do it and it will be 5+ stars in my book.
