So, I also completed this content today and can say this:
for someone who has learned to play the piano and types very quickly, with both hands, 12 seconds of this nightmare is very painful. Very.
I can only imagine how much of a problem this is for people whose hands hurt.

There is nothing to argue about here.
This is not high-level content for a select few. This is just a story quest. And that needs to be changed.
