2D Dungeon Crawler

A tiny top-down canvas prototype with tile collisions.

Controls: Arrow keys / WASD (hold Shift to run) • Space to shoot

Map: 32×18 @ 32px • Spawn: … • Player: (0.0, 0.0)

1024×576px (CSS). DPR scaled for crisp pixels.

Dungeon tunables

Adjust, then regenerate to see changes.

wallFillPercent (0–100)

Higher = denser walls.

smoothingPasses (0–20)

More passes = larger blobs / less noise.

minOpenArea (0–9999)

Fills tiny open pockets back into walls.

maxRetries (0–50)

Extra attempts if a map fails validation.

Tip: keep wallFillPercent in the 44–62 range for good caves.

Generation

Uses deterministic per-level seeds (baseSeed + levelIndex). Adjusting tunables changes the shape of the dungeon but keeps the seed mapping stable.
