Reducing the moves to 18 PLUS adding blockers PLUS more locked candies has made this impossible even using boosters. There are 12 chocolates on the board which means 18 are needed, that's one for every move. This means that to collect all the 30 chocolates ALL 18 moves must be made without clearing a single chocolate. I think I am a pretty good player having got this far with few boosters, I don't complain about impossible levels just because they are hard, but I can also see when a level is impossible to win. Do the maths! It doesn't work.
