I mostly know [1] which is a similar tool, maybe with some more emphasis on aesthetics. What kind of features (if any, but I'd guess there are) makes Dungeon Map Doodler different?
Oh wow, the dynamic lighting on those maps look really nice! My initial goal was just to make printable maps in a hand drawn style really easy to create. Lots of people draw their own maps, then spend a huge amount of time adding in all that crosshatching manually, and I thought I could save people a bit of time. I've noticed a lot of these map making tools try to do everything and end up becoming really complicated, but I'm trying my best to avoid making it too hard to use. Essentially, most people seem to be trying to make Photoshop for maps, and I'm making Paint. A tool that anybody can open and use immediately without spending a bunch of time learning the system.
