The player is required to score 340 points per second (30,000 points / 90 seconds = 333.333 points per second).
There is an abundance of licorice present that is guarding some chocolate at the bottom of the board.
Additionally, these blockers can be tough to reach because of the shape of the board.
Fortunately though, this also prolongs the amount of moves that can be made before the chocolate reaches the main portion.
Five colors makes it slightly easier to create special candies and trigger cascades, but this is weakened by the third point.
Strategy[]
Remove the licorice swirls as soon as you can to open up some board space, then deal with the chocolate throughout the rest of the level, making as many special candies as possible to reach the target score.
