Notes Ending

Notes Ending (also known commonly as Good Ending or Secret Ending) is a different variant of The Finale.

Getting the ending
Simply collect all five notes around the map (for more information on where the notes are, see here) and do the entire pre-game, if you collected all the notes and did all endings, you’ll have to go to Dummy just like the main ending. At first it will go seemingly normal until at some point, the player tries to speak and Dummy will keep that information to post-game.

In the post-game, Dummy will volunteer to hold the information and also indirectly call Cashier dumb. After Dummy keeps the information, Dummy and Cashier will still exist
