The Mermaid Mask: All Puzzles Guide

This is a guide to use if you get stuck on one of the puzzles! I will explain how each puzzle can be solved, as well as give a screenshot of what the correct completed puzzle should look like. Some puzzles will require some trial and error, while others have specific solutions.

I recommend attempting each puzzle yourself before referring to my guide. Grimoire and Sally will give you hints on how to complete the puzzle in-game, so try following their advice first. I did struggle with a couple of these puzzles a lot though, so I thought it would be useful to make a guide.
