Been working on rendering the randomly generated dungeons in a more game-friendly format. The 24-pixel tiling is looking pretty good. I've got basic doors placed and rendered. A next step will be adding some variety to the doors, to get secret doors, locked doors, iron-bound doors, bricked-up doorways, etc. I want to also start keying these to a "difficulty level" input parameter. The difficulty will also eventually drive things like trap placement and monsters.
