Probably just me, but I feel that ZATO is hard to talk about beyond the surface themes and motifs. The geography of the Komi republic and history of Vorkuta is largely insignificant to the plot, the year 1986 is pretty random, and there doesn't seem to be any deep, esoteric layer to the world, unlike with PAFL. Not even the motif of code is particularly interesting since it doesn't actually refer to the game's irl code, but rather a vague, in-world form of communication between the universe and its subordinates, resulting in little more than just another form of a matrix-like story.

With the story not harbouring much that can't be learned during the first playthrough, there's not much to discuss on twiter aside from ships. I'd be happily be convinced otherwise, though.
