The end goal at the moment is a total of 16 areas, give or take a few based on if I decide to add or cut things, with some of them being optional. Each area is supposed to have a about 4 unique enemies, with a couple of them showing up in multiple areas.
The overall planned structure is your standard soulslike, with 4 main big bads needed to get to the 5th and final one.
I'm debating whether or not I want to give a full plan description because it would potentially lose some of the exploration value if I gave the map/area list early, but it would also give a very clear picture of what needs done, and where we're at for each update.
