Most Difficult Chapters in Celeste

Just recently added, Chapter 9: Farewell is the longest and most difficult level in the game. In the 13 total hours it took me to complete it for the first time, I died 5200 times (which seems to be more than average, but still). You have to be an actual sadist to attempt to run this level deathless.

The first two screens are no big deal but the third screen broke me. Your movements have to be so insanely precise, and it's frustrating as hell when you can't even get back to the part you're having trouble with because you fell a few pixels in the wrong direction.

Almost as long as 7A, but even harder.
