I've downloaded the new demo which says 1.02, started a new run and managed to save the game. But I'm still lost as to what to do next. I can't find anyone else or anything to do other than the two statues (on the island and in the cave).
Edit 2: Ok, I just saw from another commenter that you have to press Z next to the edge to move to the next screen. I feel like this should've been explained somewhere because it's not obvious at all. So I managed to find Mads after all.
Also, I think there should be an easier way to use items from your inventory instead of having press Esc, click on the coconut and then click on hold, then leaving the inventory and pressing Space everytime I need to drink. (Or maybe there is an easier way?)
Edit 3: The game crashed when I reached the area above the sparkling chest on the elevated grassy land and tried moving to the left.
