I enjoyed it very much, but some of the levels are just too much work to go through to be enjoyable enough. Level 118 had bubble suds and had 4 doughnuts to go through 3 columns and only 2 doughnuts could be visible at a time with very limited number of moves. And it was not even titled a hard level. Some more difficult levels are to be expected, but it should not be next to impossible. I wanted to play it to reduce stress, but this game is increasing my stress, so I'll be uninstalling it.
