Couldn't get the pick up action to work. How do you do it exactly? I sat next to a rock for a bit, but it always just disappears. I also tried using E, but I think because I never picked up the rock it never worked.
Good question! I could've made it more obvious, but the rock you can pick up has a shine to it at the top left of the screen, or you could pick up food at the top right, or seaweed at the bottom right. You pick them up by standing near them for 2 seconds. You can't pick up items dropped from AI fish.
