Thick blockers and jelly can be a problem for difficult levels, especially when one level may give out fewer moves for an increased challenge. One way to combat this is to offer up a powerful, but fairly expensive (as expensive as a Candy UFO, starting from 19 gold bars apiece) pre-level booster that buffs all special candy to deal double damage for one level attempt. This means that any blast from a striped or wrapped candy will deal 2 hits of damage to blockers or jelly tiles, and Color Bombs will also remove 2 layers of jelly below whatever candy they hit.
Think this can be a good pre-level booster to have?
