Candy crush saga level 135 is one of the worst levels that you will have been faced with so far. Forming wrapped candies is difficult enough, forming two even harder, getting them together without blowing them up is as bad as it gets. More than once too.
These tips should make things easier.....although its all relative.......
Keep the chocolate in check
Don't waste too many moves on the chocolate, but you should try to keep it in check. If you have an opportunity to remove several chocolates, then it's worth it. But don't waste your time trying to eliminate it.
Work from the bottom
Working from the bottom will help form cascading matches. Look for vertical matches to maximize this effect.
Colors and combos
You only need wrapped candies on this level so don't waste your time with stripes. If you can form a sprinkle candy then you should do so. This helps eliminate one color from the screen, to make it easier to form the wrapped candies. Even without sprinkles, you should work to remove colors with little potential to improve your odds with other colors.
