Level 10249

Personally I think after level 10,000 the game is just unplayable and not fun any more. It only gets worse from here on. I'd advise you to quit.

There is a chance King will make the level easier to pass after the Candy Cup or if you take a break from the game for a week or more. You might give that a try if you don't want to quit. Just replaying the same level for so long is just frustrating. Why don't you pause playing for two weeks and then log back in an see if the game lets you pass. It might, that's what King do sometimes.
