Hey! For a FULL reset (assuming you're on Windows), you need to go into:
C:\Users\{user}\AppData\Roaming\RenPy > Search for a folder called "GarlickyCreations" and delete it.
Or on your keyboard press the Windows key + R and paste in %appdata%, then open the RenPy folder, find the GarlickyCreations folder and delete it.
Also delete the downloaded game that you downloaded, and you should be good to go.
Now, I'd recommend you redownload the game this friday for a new build I'm releasing :]
