I can give you its name too: End of the World, Part 1 and End of the World Part 2. It was a basically a Final Fantasy clone/attempt that I thought when I was younger was pretty good. Can't remember much about what made it unique though aside from a hidden stick figure fight right outside the castle.
No worries, someone found me the site it was originally on back in 2017 but lost it due to a total drive failure and only started looking for it again recently.
