I’ve finished the final puzzle on the Winter island. Is the game over now or can I anticipate new puzzles? I love this game and don’t want it to end.

Hi!
I'm not LDW, just a fan. From reading people's posts online, there's a cutscene that appears after completing all puzzles. I think you have to complete every puzzle on the main island, Isola Mystica and Winter's Eye to make it appear. I'm not sure if that means there's no further updates, but it seems to be an ending cutscene.
