Has anyone else noticed this?

Somewhere around level 12350 I noticed that even normal levels were getting hard, and nightmarishly hard levels have become almost impossible, even with sparing use of boosters. I am now getting stuck on levels for days, and I don't think I have suddenly become a worse player. I have been playing level 12413 for a couple of days now and it is starting to become bad for my mental well-being, because nothing I do seems to make any difference.

So it's time to stop playing. I'm not sure why King have done this to what was previously an enjoyable game. They have turned it into an unpleasant slog against overwhelming odds.

I expect the mods will delete this but I hope they will at least take on board the reason I am uninstalling the app.
