ok - so i figured out the answer to question #1 - i changed the 'Distort Amount' on the Dungeon Map Maker script to 25 (results below)

would still be interested in answers to the other 2 questions.
2. also yours looks a little more beveled than mine - do i just change the stroke level or something?

3. i am still learning about image size, pixels per inch, grid sizing, grid spacing, etc., and how to get things to line up properly... any tips on how to understand or make sense of all that? like.. explain it like im 5?
