I enjoyed this map uncovering game, nice work! Finding the lost city was like finding a needle in a haystack but the uncovering mechanic and all the nice little dialogues kept me going. It took me two playthroughs and around 300 days on the second one to find the city but I eventually got there.
The game reminded me a lot of the sailing mechanics from Pillars of Eternity: Deadfire, and just like that game, here they were well written. My favourites were the "you are what you eat" and "the real treasure" ones.
Just so you know but after a gameover your previous resources carry over (even if negative). I lost the first time due to running out of sailors so started with -1 and had to find a village before the day ended where I would have lost the game. The nice thing is the treasure I found on playthrough 1 also carried over so it made it a lot easier after that.
