Worldend Dominator Rosa

Im trying to make the iconic scene from "Umineko no Naku Koro ni" series playable, where Rosa and Maria trying to escape from rokkenjima after all the family is slaughtered by the Golden Witch. Anyone that need references of the story should watch Episode 11 of the anime, or Episode 2 Vol. 5 Ch. 26 of the Manga, or Ending of Episode 2 from the Original Visual Novel. *I will update the assets if i have time.
