This game is ALMOST perfect

I love this game so much and thats why it felt so bad after that ending. I beat the entire game without checking internet or even GUESSING. So if I lock in a person Im 100% sure who is he and how he died. The ending tho... You can't beat the game successfullly for the first time with only deduction and thats a horrible thing for a deduction game! The game even let's you know that a much shorter travel will take 3 DAYS by boat (one of the chapters where they try to run with treasure). FOUR of them went in to a boat in which they will travel for WEEKS. How am I supposed to know IF they survive and then where they are? Its not guaranteed they didnt just split as soon as they arrived to a country. Its so stupid and it completely ruined the experience for me.
