Extra moves will not actually help here. As I'm sure you've found, if you're not on schedule to win, the chocolate will close you out several moves before 20, let alone 30. I can only assure you that it is possible (I've just revisited the level and completed it on my third attempt). You just have to keep at it.
No, everyone else didn't have 40 moves. The first few players had 40 moves which proved to be absurdly easy. The majority of players, including me, had 17 moves and passed it anyway.
Miss you? I doubt it. And why would anyone miss you if you can't make a gracious exit without wishing that those of us still enjoying the game be deprived of it?
There really isn't anything to say here other than it's not impossible. In fact it's not even particularly difficult. Striped candies alone will not help you though. You really need to be looking for combos. A wrapped/wrapped combo on the bottom row of the main playing area, for example, will net you a minimum of 10…
It was announced weeks ago that 2825 would be the last level offered in the old format at king.com and that further updates would be available only through Facebook and mobile apps. There is no 'problem' to be rectified.
Where did you get that ridiculous idea? Success costs and right here is where you start paying! (Oh, and it's not impossible - I've done it on the reduced moves - twice in fact - without boosters)!
