Two of my great loves, deciphering fictional languages and archive-based mystery games. Very cool figuring out this world.
I don't know if this is within the scope of something you could (or would want to) change post-jam, but the ability to highlight new words by mousing over them and then click to search means that you don't actually have to read at all to unlock all of the documents if you just go through what you have clicking on everything green, which seems to work against the investigation process.
Anyway. Big fan of your work.
