I think this game is pretty good, to be honest. The are lots of details and curiously, reminds me somehow of Commodore games. There's only one thing that I suggest to upgrade: the start.
At the start, you're given lots and lots of text. And if a person thinks that's tedious, I won't personally disagree. At instance, you could have put a interactive presentation of the story with a cool song, rather than write lots and lots of text.
If this is a demo, I hope you to expand it!
Anyway, good game and good luck! :3
Ahh and, can you check my project to revisit it? Link it's here: https://ivandur112.itch.io/dtsi-2026demo
