Avoid freeing liquorice locks but if this happens, control the chocolate to prevent it from covering the whole board but do not waste moves clearing them all since you only have 14 moves.
Also, avoid ingredients from falling to the sides as it may be hard to clear all chocolate in 14 moves.
As usual, vertical striped candy help bring down the ingredients directly. There are only five colours so making horizontal striped candy; also making colour bombs is easy, these free the liquorice locks which you do not want. Making vertical striped candy which you want is harder due to the narrow board.
