unfortunately no. Files that are available to download are build version (when you build the game from the project).
While the script and all the renders are available and can help me make the game again till where its currently at, but all my assets (characters, maps, outfits, etc.) and all the progress I already did for chapter 1 is gone. So, I have to make them all over again from scratch.
That's why I decided to rather make a new game with a fleshed out story than continue the old game and try to make the assets again and make sure they don't look too different from the ones which were already used in the prologue.
