Perhaps it is true what they say about eldritch horror being more suited to text simply because our imagination does the rest of the work.
I like that the descriptions don't run on. There's enough ambiguity to create a sense of paranoia but enough detail to feel specific and tactile. I liked the sequence at the top of the lighthouse for the same reasons - it's spooky throughout but the moment you get to inspect it you end up re-evaluating what happened. The hidden text could be a bit of a bottleneck for some people because the hint isn't listed anywhere, I figure that's one feedback you will get often. I was lucky enough to find it on my first playthrough. After that, I ended up checking a lot of places, only to find nothing. When it works, I think it can be a great moment; it really put in me in the headspace of a paranoid Lovecraftian protagonist. I also liked the indirect nature of figuring out the laboratory password. All in all, a fun little game.
Good luck with your degree!
