Yea, most devs allow prior saves to be directly ported over to the newer version.
A few will directly point out in the description if you need to create a whole new save file.
Launch the new version and your old saves should be visible.
This is hands down my favorite Renpy game. You gave us so many options where we needed it, which is super uncommon. The characters are beautiful and well flushed out. I enjoy all of the story plot points that are heavy and serious, and was happily emotionally invested. Full support and good wishes to you Raybae <3
I hope that you find time for your own happiness and passions. 10/10
