Don't be put of by negative reviews. This is a very challenging game at times which makes it enjoyable. You have to work out solutions to difficult obstacles. Some good unique features. Noticed people getting stuck on level 82 took me 3 attempts to work out. You have to use the power ups specifically I used a bomb made from a match 5 or more then shuffled to get into the frozen area, then detonate using hammer which cleared enough to finish game excellent.
