> Slowly piecing together the fates of all the people on the ship is deeply satisfying, sorta like a sudoku puzzle.

Return of the Obra Dinn relies completely on the fact that you can make guesses and the game will confirm for your benefit whether or not those guesses were correct. The information you're "piecing together" is not actually present in the game - you have to guess it, and sometimes the game will tell you that that's what the game developers were thinking too.
