Why is the game running so fast?

Another thing I've noticed is that the jerkiness and speeded-up gameplay do not occur on every level. Since I reported this issue ten days ago, I've completed approximately 8-10 levels (currently at 4638), and I'd say the gameplay seems "normal" on at least half of them. I guess I'm tolerating the problem because it's sporadic (if it was happing on every level, I wouldn't be playing)...but it's SO annoying when it does occur!

how do I get it to speed up like that. I don’t even have the 2x button anymore? I much rather play at high speed
