| `ghost_reset_distance` | float | `10.0` | Minimum distance (units) between the player and the nearest ghost before the player is snapped back to the maze start. Increase for a safer buffer, decrease for higher tension. |

| `minimap_enabled` | int | `1` | Set to `0` to disable the minimap overlay entirely. |
| `minimap_width` / `minimap_height` | int | `200` / `200` | Size in pixels of the minimap rectangle rendered in the bottom-left corner. |
| `minimap_margin` | int | `16` | Padding (pixels) between the minimap and the screen edges. |

## Minimap Overlay
The minimap is a HUD overlay that reuses data parsed from `maze.txt` to draw a scrolling view of the maze. Player breadcrumbs are recorded every second and rendered as solid discs so you can retrace recent movement. Ghosts are displayed as border + fill circles that remain unrotated while the player arrow rotates with camera yaw. Tweak the overlay’s sizing, colors, and zoom via `ghostland.json`—when `minimap_zoom` increases, the entire map scales up; breadcrumb/ghost radius and colors are controlled by the dedicated `minimap_breadcrumb_*` and `minimap_ghost_*` keys described above.
