How do I delete my saves? I want to start over from square one. I use the windows version.
go to the saves folder and delete thator give start
If you hover the save file with your mouse and click "delete" button on the keyboard it should show the question if you want to delete the save.
Or you could go to the folder where saves are kept and delete saves from there (Users*name*\AppData\Roaming\RenPy\)
In the save screen, press Del/Delete on your keyboard when your cursor is on one of the saves and click yes/delete to remove a save from that slot, repeat for each ones you have in there.
