Nice to have more control over themes and the avoidance of too many themereplacementvolumes scattered all over the level is a nice addition, too.
Will be really handy if used in conjunction with the “gameflow” editor on which you work. Entrance, exit, bossroom or library with clustered theme control will be great.
Studying the screenshot of your debug dungeon I found some problematic areas in the layout. Stairs that are at room borders are not only visually very ugly but can break
gameplay as unreachable areas where doors meets stairs could be generated.
Is it possible to limit heightvariations to corridors and suppress them near rooms? I really like having heightvariations in the random levels but it’s problematic without control.
