Spawn rooms, in blocks. 0 = automatic (sized from the grid).

Attacker spawn W × D Defender spawn W × D

Flow & combat

Cross-links make loops & flanks (Rule 2). Every choke is guaranteed a flank or gets widened (Rule 3). Jitter offsets rooms so no lane is a dead-straight alley (Rule 5).

Symmetric Carved pit layout Underground layer

Terrain

Rooms become flat clearings; corridors ramp between them so every join stays walkable. Relief rolls the clearings up and down; the ridges between lanes do the sealing.

Block textures

Swap any block the theme uses — click a swatch to pick from the atlas, × to go back to the theme's own block. Picks stay on when you change theme.

Atlas (optional)

The kirka atlas is built in. Load another texture.png to preview with it.

Border barrier

The rim seals the footprint so the open map can't be walked off. Risers are quantised to the rim step, never below 3 — unclimbable.
