Rooms: place rectangles, connect centers, add loop links, then rasterize to tiles.

Mazes: carve a classic grid maze, then optionally punch a few extra loops into it.

Caves: random fill + smoothing. Good later for underground or ruin styles.

Hybrid: place rooms first, then roughen selected edges for a more natural look.

Randomize: mix together the room, cave, and maze styles for more chaotic results.
