Thank you for playing !
Have you tried to use the "hint" 4 or 5 times ?
Because it will show you, in red, the four keywords you can use to advance. I'm testing all the hints branching right now and I'll make a quick update.
If it's really not working, let me know, I will provide you with the keywords. Just tell me then what caught Elias attention during his POV so that I can give you the right ones. :)
