Sorry for the late response, I haven’t looked at Itch in a hot minute.

1. In the game folder find the renpy/common directory. Open the file called 00console.rpy in a text editor.
2. Change line 108 where it says config.console = False to config.console = True
3. Open the game and try pressing Shift + O. A console-looking thing should open up. (If it didn’t, maybe try deleting 00console.rpyc and relaunching the game, forcing it to recompile.)
4. In the console, type persistent.true5_choseEnd = False and hit enter
5. Restart game

whOa, cOoL ReNpY hAcKs!
