Proto:Lufia II: Rise of the Sinistrals/Doom Island
This is a sub-page of Proto:Lufia II: Rise of the Sinistrals.
The Doom Island map (location index $F0)) in the prototype is in a very early, unfinished state containing only a single layer. There is no collision data, no functioning exits, and the music is set to play the town theme. Notably, it resembles the Doom Island layout from the first game.
