Hello, there! Thank you so much, I'm really glad that you've been enjoying the game :DD I might be able to get you back to the point before the final battle so you can explore and grind some more before attempting the fight again. If you open the extracted game folder, go to a folder named "www", your save file(s) should be inside a folder named "save". I would like for you to send me those files to my email daylieaf@gmail.com and I'll see what I can do from there!
