Thanks!
Yeah, this is basically a pile of meticulously-crafted tech, aaand then I ran out of time to make the game itself better.
The narrator is pretty complex as you guessed. It's not quite perfect, but I like it a lot overall and it was a great learning experience. I ran into a lot of issues such as robots can't say "sky" due to the TTS, and had to write things in weird ways all the time, but overall it was so much fun to mess with.
It's capable of switching lines and certain words randomly, as well as counting to a hundred. I definitely like how it makes it sound a bit less "NPC repeating the one line they know when you talk to them" than usual (especially when clicking on the resources!)
