This code was figured out by one of the editors, Lane! replace harukiENDBclear%22%3A%22true with harukiENDBclear%22%3A%22false in order to play through his initial madness ending (thanks to Cam, who let me know)
I asked Naofi to upload this .sav file with this edit to Google Drive! Add it to the game like how you added the Patch! (Be sure to Replace it since your computer will ask)
