What's the changes after multiple playthroughs of You Must Build A Boat?
Agnetti decorates your ship depending on how many Ace levels you have. So far, for 2 Aces (i.e. restart the game for the first time), she puts up a figurehead and for 3 Aces, she turns the walls of the ship into metal sheets.
I daresay she does other stuff for mor Ace levels but I haven't got there yet.
