Thanks for your kind words and for taking time to list your suggestions. There was a whole "shadow process" during the games creation, where our team was trying to understand and figure out how to translate our nicely and coherent written story into a defined game loop. This was a true challenge for many reasons - the parts where we didn't do so well ended up being the arbitrary clues you found. The challenges got even more tense towards the end of the story - so I had to cut some bloody corners to e. g. let the player find "at least some kind of code" :-D To me this overall process (getting from "no idea how to do that" to "okay, it works pretty well") was really interesting and satisfying. And now all these encouraging and confirming comments like yours coming up here, makes me so happy.
