Funny enough, I think the two of us started our projects on the exact same day, or at least first posted on Twitter, haha. He's doing some really cool stuff too!

I like both, but I'll probably 'move forward' with whichever one has masking working in a non-obtuse way first. With dungeon scrawler there is a pre-set that uses masks, but I've completely failed to figure out how to set it up on my own. I'd be willing to pay one-time fees to unlock art packs or other content to support the creators. But the dungeon fog style of wanting me to pay monthly... just... no.

In this context, you mean masking to hide parts of the map from player? The crosshatching effect on my maps (which can be changed to all sorts of different styles) is created using a mask, so I just wanted to clarify.

If that's what you're going for, there isn't a super obvious way to do it in my software yet, but after making your map, you could add a new layer, switch to the Hatching Tool, choose solid black hatching, or any other solid image and draw over any parts you want to hide. Then to uncover it, just use the erase tool with all but the hatching checkbox selected, and it'll unveil the parts of your map underneath.

If you were thinking of something else, let me know and I'll answer as best I can!

This one though seems to work well on mobile, dungeon scrawl I could not get to work properly, at least when it was posted on hn not too long ago.
