Quality has gone down but still enjoyable

I just recently re downloaded this game after not playing it for about a year, although the game gets harder as you progress it is extremely difficult to get hearts to upgrade and buy characters (2 hearts per game) and any extra you win in the spin challenge. Not to mention as I progress my characters freeze and I have to save and quit. Would be much better if the quality was good, but still fun to play.
