Part of Tower Defence.

  1"""Level data for the Tower Defence port.
  2
  3An original level designed for this port (the upstream tutorial's Tiled
  4map is not redistributable). `level.png` is baked from Kenney's CC0
  5Tower Defense tiles plus a procedurally drawn sand path that follows
  6`WAYPOINTS`; see `ATTRIBUTION.md`.
  7
  8- `WAYPOINTS`: polyline the enemies follow, in world space (px). The
  9  ends sit off-screen so enemies enter and leave smoothly.
 10- `TILE_MAP`: 15x15 grid; tile id ``7`` is grass and is the only tile a
 11  turret can be placed on (``2`` = path, ``5`` = decoration).
