Absolute delight! Got stumped more than once - thought it was (of course) a flaw in the game. NO TIMED challenges which turn me off, but timed moves (must complete in a certain number to get "the gold") - which I could have done without, but admittedly raises the challenge as well. Had to leave game and come back with a fresher mind at times. Cute story line befitting the game. Best of the best, you can finish levels (67in all) and than go back to getting the Gold Stars by replaying the levels, enabling you to finish to the end without being perfect.
