How to back up your save slots
Right now there are only 4 save slots. If you really want to save something and keep it while you work on more things that require more save slots then do this:
Go to %localappdata% and then the Shadowforge folder.
Alternatively zip everything there or just move them to another folder.
When you need to return to this drawing and your save slots are full, copy them back to the %localappdata% Shadowforge folder.
You don't need programming knowledge to do this, all you need is to search for %localappdata% after pressing WIN key + R.
Here's just a reminder what it saves:
Time worked on your art piece.
10 layers.
9 animation frames.
A lot of code that must be saved for the program to return to where it was.
Back ups.
First save slot is marked as _1, second save slot as _2 and so on.
Cheers.
