You have 10 moves to collect 176 candies. (17.6 candies per move)
If either blue or purple is on the left side of the moon scale, the player has only 5 moves to remove all 88 of that colour since the colour removed will not return for the remaining 5 moves, so it is impossible to win if you do not finish the order when moon struck is in effect.
The candy bombs in the middle of the board are hard to defuse.
The dispenser may hinder the progress of collecting candies.
The moon scale is relatively unstable, making it difficult to create huge cascades required to meet the order.
