Well a 1.1 extract just came out on pateron plus this
makes it sound like it's what Malin wants to work on next.
On other hand each 1.1 needs it's own unique half (that can stil fit in other paths like the Chen talks in 2 about him building up to telling Step that he knows that Step that's a Re-Gene) that also takes into account romance, polys, suspicion (though at least for Ortega it has to be somewhat low in order to get here anyways) and probably a few other variables. All this taking so long was one of the reasons that even though 1.1 won a pateron vote a while ago it still got push back. So if it starts taking too long again I can see being pushed back one more though to finish the rest of puppet paths for chapter 1.
Excerpts from these paths have been appearing regularly on Patreon since 2023

As far as I recall, the author said that 1.1 are more pleasant and easier to write than the puppet stuck endings, so he would leave them as the last.
But can we trust his words? I got impression he's working on whatever he feels like depending on his mood. Writers
There are 4 endings left besides 1.1 - we stuck in the puppet, but it was the Impostor who ended up with broken legs. They are quite exciting imo, judging by the excerpts.
