"The Toymaker's Box" [1111 words], speculative short story

Experimented with a piece that is entirely dialogue here. Warning: it's another weird one, so don't go trying to take it literally. I'm polishing it for speculative fiction literary markets, so it's trying again to show not tell. Hence some purposeful ambiguity that the reader is supposed to fill in with their imagination, but I'm curious to see if it is successful in that sense. Looking to assess how it hits emotionally, what the pacing feels like, if it sags or stays sharp, and if the dialogue cracks at any point.

Crit here, which looks short except when you see it continued in a reply-- the whole crit was too long for reddit to post as a single comment.
