The appearance of the game has changed!

I don’t understand what is going on! I can’t even play. I’m level 6377 and this is the first time I have ever seen drastic changes like this with on explanation from King. There is a strange green arrow that doesn’t seem to do anything, 4 candies in a row make a knot there are strange lines on some candies and in the side bar there is a picture of 3 color bombs! This doesn’t make sense. There have been times I can make any move when the green arrow is on the board but it doesn’t reshuffle. I HATE THIS!!!!! What is going on?! Fix it!
