Nice demo. I really like the music, the guitar fits well and the art work is simple but effective and adds to the game. I wonder if there will be other guitar tracks for other areas of the game such as when entering darker or more dangerous areas? and another track when encountering unknown characters or situations.
The Archive is a nice feature, it would be cool if there is a search bar which can handle two keywords and search the whole archive, reordering it to the search and highlighting keywords. So you might enter a region name + second keyword. That could be a fun way to delve into what you already have learned rather than the game track of this for you, where it might say when you arrive at a location 'here is the ruined hunters cabin the tinker said you will find something written on the inside wall..' etc. Typing hunters cabin would jump to that part in the archive of conversations.
Also you could perhaps add the ability to highlight a sentence or paragraph and right click to save it as a personal archive, another option in the side menu. Which kind of acts as a note book, adding what we might consider important info to quickly re-read later.
Anyway keep up the good work and i look forward to playing the game when its finished.
