Level 2854 is the fourteenth level in Tricky Tower and the 227th mixed mode level (222nd jelly-ingredients). To pass this level, you must clear 27 single, 36 double jelly squares and collect 6 cherries in 22 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Sugar chests block the ingredient exits. While two of the keys are only placed in two-layer frosting, the third one is hidden below the liquorice shells.
Saying about the liquorice shells, they are below the ingredients, and they also have jellies beneath.
The 3 ingredients given on the board are only half of them, and 3 more need to spawn.
All things above shall be done in only 22 moves.
The jellies and ingredients are worth 159,000 points. Hence, an additional 161,000 points is required to earn one star. 
There is no strategy other than breaking liquorice shells. You need the colour bombs to initiate mass combinations.
Element Spawn Notes
If there are fewer than 3 ingredients on the screen, then the board spawns up to 3 ingredients when possible.
The maximum number of ingredients on the board is 3.
↑ (27 single jellies × 1,000 points per single jelly) + (36 double jellies × 2,000 points per double jelly) + (6 ingredients × 10,000 points per ingredient) = 159,000 points
