You only have 22 moves to clear 54 double jelly squares, together with the liquorice locks. That means, you need to clear an average of 4.91 (5) one-layer jellies per move.
The jellies under the teleporter and liquorice locks may be hard to get rid of.
There are only five colours on the board, though, so you can create special candies more easily.
Candies cleared under the pink teleporter will not be replaced till the liquorice lock over the blue teleporter is cleared. Either of the two candies at the far right bottom can free the teleporter but not the third candy from the far right bottom.
The jellies are worth 108,000 points (54 double jellies x 2,000 points per double jelly = 108,000 points). Hence, an additional 12,000 points is required to earn one star.
