The Entrance Randomizer allows you to twist the world upside down and play the game. It should mostly follow the standard VT rules for settings on everything, but it introduces a new option "Shuffle"
Shuffle Dungeon Entrances/Exits between each other and keep all 4-entrance dungeons confined to one location. All caves outside of death mountain are shuffled in pairs.
Use Dungeons shuffling from Simple but freely connect remaining entrances.
Mix cave and dungeon entrances freely.
Decouple entrances and exits from each other and shuffle them freely, only ensuring that no fake Light/Dark World happens and all locations are reachable.
Madness without the world restrictions. Mirror and Pearl are provided early to ensure Filling algorithm works properly. Deal with Fake LW/DW at your discretion.
