Goal: collect all ingredients and reach 22,000 points to complete the level.
Tips: here there are 2 ingredients (1 each hazelnut, cherry) to bring down. Process keys as quickly as possible. If you can also unlock that color bomb in the middle, that would be nice too. Once the ingredients are out, bring them down to the bottom like the usual. See how this level is done in video below. Good luck.
