Ah, no worries at all, thanks for playing it! Regarding the combat, the page description said no combat initially, but I actually ended up adding a bit of action late in dev because I thought players might get bored just walking around without any tension.
As for what to do, you just have to explore the island and find the hidden treasure near the main landmark first—once you grab that, the path back to the ship opens up. Appreciate you giving it a shot and leaving feedback❤️
