## Pixel-Boy and AAA — Ninja Adventure Asset Pack

- Files: everything under `assets/src/ninja/`, kept at the pack's own
  relative paths:
  - `Backgrounds/Tilesets/` — `TilesetFloor`, `TilesetNature`,
    `TilesetHouse`, `TilesetField`, `TilesetWater`, `TilesetElement`,
    `TilesetRelief`, `TilesetReliefDetail`, `TilesetFloorDetail`,
    `Interior/TilesetInteriorFloor` (terrain, paths, cobblestone, trees,
    boulders, houses, fences, fields, ponds, planks, the mine mouth);
  - `Actor/Characters/*/SpriteSheet.png` — Greenman (the player), OldMan,
    Woman, Inspector, OldMan3, Villager3, EggBoy, Monk, OldMan2;
    `Actor/Characters/*/Faceset.png` for the six speakers;
    `Actor/Animals/Pig/SpriteSheetPink.png`;
  - `HUD/Dialog/FacesetBox.png` (the portrait frame);
  - `Items/Treasure/LittleTreasureChest.png`.
- Sources: https://pixel-boy.itch.io/ninja-adventure-asset-pack and
  https://github.com/pixel-boy/NinjaAdventure. The pack's GitHub repository
  ships only part of the pack; the full-pack files were taken from a public
  project that vendors the unmodified pack
  (https://github.com/MarioLDD/Kuroshiro-adventure,
  `Assets/NinjaAdventure/`, whose `LICENSE.txt` is the same CC0 text).
- License: **CC0 1.0 Universal** (public domain dedication),
  https://creativecommons.org/publicdomain/zero/1.0/legalcode. Verbatim
  text: `assets/src/ninja/LICENSE.txt`.
- One file shipped as a palette PNG (`Items/Treasure/LittleTreasureChest.png`)
  and is stored as a pixel-identical RGBA conversion, because the PocketJS
  PNG decoder reads RGBA only; no pixels were altered.
- Credit is not required by CC0 but is given: **Ninja Adventure Asset Pack
