Edna & Harvey: Harvey's New Eyes

There are three endings to the game. It is imperative that after defeating Mother Superior in Chapter 3 (checkmate) and unlocking the story-related trophy that happens right after, during dialogue (hare scare), you make a separate save!

When you finish the game and are in confrontation with Dr Marcel, you will have three dialogue options, which corresponds to three different endings to the game. For this trophy, you will need to see all three endings. To do so, pick an option, watch the cutscene and wait until the main credits begin to roll. Once they do, go back to the main menu (), reload the save and repeat the steps to get to the endings choice again and choose another ending.

Note that for one of the endings ("Contradict"), you will need to click that option several times before the ending starts.
