--[[
Convert a graphical dungeon into one for Pico-8 Lua Minima.
X = wall block = 3
# = pit = 2
~ = under pit = 1
space = open area = 0
Note that pits and under pits are now ignored by Minima. We're using
them to track location of ladders for ease-of-use, but they don't
really do anything. Likewise periods can be used to map out points
of interest, but they get ignored by this converter.
