I finally managed to complete this level, but it was with a lot of luck and a few boosters. It was the most difficult level I've ever done. There must be something wrong with it.
The only way to pass this level is to keep the liquorish swirls intact in the conveyor belts. However with so few moves this is virtually impossible. This is currently classed as an easy level, when in fact it is the most difficult I have encountered.
