TIL the word "moor"! :D
I think one of my favorite parts was reading your level messages in the corner, haha - it added a lot of character and kept me wondering what would happen next. It goes to show that some sort of story is immediately engaging for a game.
I keep thinking that it'd be fun to see a version of this with more game mechanics. Maybe holding the mouse down makes the anchor unravel quicker so you can avoid obstacles (like fish). Or maybe the rock to anchor to is moving for some reason, so you have to plan in advance where to aim (not sure how that would make sense narratively, haha).
Anyway, great job finishing your first game jam!! I'll look forward to seeing your next one!
