La Mulana for sure! It’s a game where you play as professor Lemeza Kosugi (i.e. Japanese Indiana Jones) exploring an ancient temple. I admit that I did not have the patience for it. The map is huge and exploration is very non-linear. You also have to solve fairly obscure puzzles. If you really wanted to give it a go, I’d keep hand-written or typed notes separate from the in-game notes. They only let you save so much data at once, and you need more notes (or a good memory). I still kind of loved exploring the maps even partially though. It’s pretty huge and ambitious in scope.

The combat and movement are not fantastic though. Not bad, but they feel very limiting compared to typical metroidvanias that let you style on enemies as you get better at the game. The game is not very shy about how it enjoys killing you too! I respect it, but it was tough for me to enjoy.
