All the games I played around that time are mostly a blur but I might be able to find it in my old saves, do you know what it was called? Or maybe a couple words? Also, if you can't really remember that much the way to find all your saves for all Ren'py games is to go to "C:\Users\"yourwindowsusername"\AppData\Roaming\RenPy" in the files explorer, and you might be able to find it in there if the title isn't abbreviated or something like that, or it strikes a memory. If you're mobile, though, there isn't really a way to find all those save files unless you hook it up to a pc and go through a whole process to look at appdata I think.
