I would like to suggest a map or memories overlay.
something like the options menu where you can review each major location, the links between them, and the limited and unlimited resources available there. maybe even special actions and their requirements, just to help in planning runs and reviewing things
suggest a message pop for santorini exploding even if you aren't there, possibly pausing in progress travel actions there?
also I feel like the tram between santorini and atrapos could be split up, I was travelling back to atrapos when santorini exploded but only had 30s or so of travel left and hoped I would survive to explore things I skipped instead of re-looping. similarity I died travelling to santorini but only after the action completed.
