Their big feature for the next major release is a Mac version, and until then it works quite okay in wine. Probably better in Linux/Wine, as that tends to have fewer graphics bugs.

My enjoyment factor of both DungeonScrawl and DungeonDraft is a bit different, as with 'Scrawl it's awesome sketching a big event location, whereas with 'Draft I get a Bob-Ross-ian spark when adding minor details. A candle here, a floating corpse there, some cobwebs and fungi…

I can pair DungeonDraft with FoundryVTT, where you can get virtual lighting support imported from the maps. So you don't have to "paint" your walls twice, once for the pure visuals and once to see where vision and movement is blocked.
