Yukowsky asserts in the penultimate chapter of his climax that the readers are required to search for and submit a solution to the situation he's presented. And that if no reader can solve it, then [dissappointing ending] will occur.
In the next chapter an ending is presented.
Specifically the happy, "there's a solution" ending.
Is it known whether that was actually the result of the actions (or inactions) of the readership? Or is that merely a 4th wall conceit / community engagement prod.
Was there truly any uncertainty in the author's mind about how the story would progress?
