It's a beautiful game and through its visuals and audio I was immediately immersed in the presented world. The game loop is interesting and the intertwined story elements engaging.
However, sometimes it felt a little frustrating as I didn't fully understand why certain choices turned out one way or the other. It's unclear how strongly my stats affected the outcome of given choices.
Nevertheless this game is spot on with the theme and I think it has a great potential if you extend it with some elements and story progression. Maybe you could do certain upgrades for some currency once you're back from an expedition to better equip your crew for the next adventure.
