Lol, I tried posting the answer
right as the automated backups happened. Okay, let's try this again... What you need to do is nuke the saves from within the game's directory (wherever you put it) and also the persistent saves located elsewhere.
- For Windows OS, it's ...\[YOUR UNIQUE USERNAME]\AppData\Roaming\RenPy\ExcitingGames-1556737783.
- For Mac, it should be .../Library/RenPy/ExcitingGames-1556737783, iirc.
- And for the Linux OS it'll be .../.renpy/ExcitingGames-1556737783.
As I'm not very familiar with the latter two operating systems and do not have a machine that runs them on-hand here, I can't check them personally but hopefully the above information will help to guide you toward them if you run either one of those systems. And for Windows, that's the correct location as I just checked prior to making this post. Hope that helps! Cheers and good luck! Have fun.
