I think they could make adjustments to the story in response to feedback. But without altering the actual plot. Just things that people have pointed out like Wuk Lamat being afraid of heights then jumping from great heights without issue, not repeating things as much, moving some dialogue from Wuk Lamat to the scions who understand the subject better, adjusting the part of the track that Smile starts at (if it started from the beginning it would be less obnoxious, but currently it starts midway through and blasts your speakers), more solo duties for things like cooking, the train part and Wuk Lamat winning the Alpaca. Send in a few more scions into Living Memory. Just stuff people have pointed out a lot.

They can't really reverse the story. Some people did not like the first half of the story, and some people did not like the second half, so not everyone's going to universally agree with eachother on which half of it was a problem.

I think another problem with it was that, according to interviews, it was basically a story about AI, how we will begin to make AI versions of ourselves (people are already) and then run out of earth resources to power all the past AI versions of ourselves. Which we are seeing play out with heavy investment in nuclear power for AI and companies like Google/YouTube frantically trying to delete the accounts of inactive/deceased users to help keep disk space sustainable. The fact this was the inspiration for the story but that it wasn't entirely obvious is maybe a problem, because instead of understanding the "point" of the story, a lot of people are wondering what it was all about.

Really another thing that would probably help people get through the MSQ at a higher rate is having characters voice act while following you around like many single player games do, as opposed to having to enter a cutscene.
