Hey nice theme! If I do say so myself ^^
I really enjoyed playing, I think I did everything? I got 35 max coins and I beat the ship, but then I'm left in the next room with the broken boat. Also there was a door on the top of the map that doesn't lead anywhere? I thought it might be a secret :)
Grabbing onto a ledge is super satisfying, I had a bug a few times where I'd get thrown the opposite direction after climbing up? I was using gamepad if its related.
Overall great experience, I'd play a proper version of this :)
