The presence of five colours makes it easy to create special candies.
The jellies are worth 24,000 points. Hence, an additional 46,000 points for two stars and an additional 86,000 points for three stars have to be earned through matching of candies.
The two star score requirement is increased by 16.67%  compared to its Reality counterpart.
The three star score requirement is increased by 10.00%  compared to its Reality counterpart. However, it is not too hard due to the moon struck.
The regular icing are positioned in such a way which heavily reduce available board space and make them quite hard to clear. Once they are cleared though, cascades can easily occur.
With respect to the three star target score, 20 moves are insufficient to boost the score by a huge amount of points to meet that target score. In fact, it is easier to use the 15 regular moves to clear the regular icing so that moon struck makes it easier to special candies and cascades.
Moon struck removes candies matching the colour on the left side of the moon scale and lasts for 5 moves. This makes it much easier to create special candies.
