Tsu's WorldMap Unlocker

This mod does not edit, modify, or mess with savegame data, it simply rewrites the system originally in place for deleting the in-game map icons off the worldmap once you completed them. Now you can replay completed levels on your current save without starting over! Once a level is finished, it’s marked complete, but you can still revisit it as often as you'd like. An added "Ascend" button also lets you go back to previous map layers. Additionally, once you've collected all six keys, the mod reveals every "special" location, removing the RNG element and allowing you to really take in those locations. Note: This will not unlock items or progress for you. You must still play and complete each level as usual—it simply lets you replay them.
