I ended up finding, I think 30? I had to stop myself or I would have been sat there forever trying to find the rest hahaha. I think I did explore all of the map regions though! I think you did a good job with the "you don't know anything" aspect! It came across well, and genuinely this style of exploration puzzle-y based on environment cues is fantastic and my favorite type. =D I'll probably try and sit and find them all later
