This game was one of the first few games written in the current incarnation of Texture, presumably meant to showcase Texture's strengths and capabilities. At the moment, these are very similar to that of a limited parser. Like a limited parser, Texture lends itself to focusing on a small collection of verbs while giving the reader some ability to interact with the environment (compared to, say, purely choice-based games), and it is used here to simulate making and redirecting conversation, to surprising effect.
There is an elegant twist in this, and it's pleasingly circular, topping off the whole game like the proverbial cherry on the ice cream. Predictions is brief and very largely linear, but hides a positively delightful surprise.
