Really fantastic game! 

This is an updated review.  Ive had this game over a year and it is one of the best games on the app store.  I have come back to it over and over!  I was sad to get to the end of the adventure mode!  But I just reset and go again. Lots of replay.  It is mentally challenging but not too frustrating! This is fully worth the cost! Highly recommend!  
