Hi! Depending on your system, I've included instructions below:
For PC -
1. Search for %AppData% using your Windows search key.
2. Once inside, look for Roaming.
3. Click on the Renpy folder to find "Salvus Aries".
4. Saves folder should be inside with your saves!
5. Another saves folder is inside the unzipped Salvus-1.0-PC folder.
6. Click on salvus-1.0-pc once unzipped.
7. Head to the game folder. 8. Inside is another folder called "saves".
For Mac -
1. Click out and above your taskbar you'll see the button "Go". Hit "Go to Folder" next.
2. Enter ~/Library
3. Look for the Renpy folder and double click to access Salvus Aries
4. There should be a saves directory inside with your game saves.
