Unlike normal walkthroughs, in Nice Game Hints you can select just the puzzle you want hints for. Here are listed the puzzles for "Chapter 2 - Edna's Hideout" in Edna & Harvey: Harvey's New Eyes. The guide you choose only contains information about that puzzle, reducing possible spoilers for other puzzles.
