Hey Biology,
I'm sorry to hear you were having issues with saves/scenes.
If you're looking for a clean install on Windows: Delete the entire saves folder within your AHITR folder, and, be sure to delete the folder in the Renpy folder within the Roaming folder that's in the Appdata folder (Windows key + R and search "appdata").
The path should look like:
C:\Users\YourNameHere\AppData\Roaming\RenPy\AHouseintheRift
Delete that folder too and you should have a fresh install.
On Android, locate the AHITR directory (Should be Documents\ahitr_storage\game\).
I hope this helps out, if not, please feel free to poke me here or on Discord o/
