I enjoy the game for the mostly but have 2 major issues. 1) there is no confirmation before using gems to add moves at the end of a level - if you accidentally push the continue button it will spend that 1000 gems for the 5 extra moves if you have them available. Annoying and wasteful when you can fully refill lives for 1200 gems. 2) some of the levels are extremely difficult to get 3 stars. I've won levels with 10+ moves left and several power ups on the board and still only ended with 2 stars.
