As long as you didn't make them before hand specifically for this jam, yes. 👍
From the rules:
You may use pre-made, publicly available, and purchased assets, as well as GDevelop's built-in asset library, or other assets you have the legal rights to use. Just remember to credit properly.
Ok, so if I already have some sprites laying around I can use them, but I can't make them SPECIFICALLY for the game jam. Ok, good to know. I probably wouldn't anyways because I want all my characters to be unique, but this is still good to know
