Thanks so much. Yeah I forgot to even hint at where you should build a ship - it's at the first island (the top one) in the sea. Sorry about that. I do plan to keep updating and balancing for the next couple of days, if you wish to try again.
I tried to go back, I figured out that that's where I should build the boat, but I still couldn't find a place that let me, is it supposed to be built on the water or land, or is there a special place? I might've done something wrong, but I'm pretty sure I tried everywhere :P
