For the first 30-40 levels the game is relaxing and entertaining. But, after level 40 on up butterfly's and the hard crystals, takes the relaxation and fun out to the dump!!! Seriously, the ability to match is far too difficult. Plus even though the set amount of butterfly's have been gathered, if a butterfly gets to the top the game is over! It happens far too often. So, I'm generous in GIVING two stars. No need to reply. I'm not interested in useless words.
