I would recommend either of the two mentioned in this other topic (with a preference for Hunger Daemon). Do you regularly play adventure games? - #16 by besmaller
They are both free, fairly short, and some of the best I’ve played. You will need to download a Z-code interpreter client, like Glulx, or Gargoyle, to play them. (or I think there’s an online player on the pages for these games, though I tend not to like those).
