Made for **GameBoy Jam 4** — a four-shade tileset and ninja sprite set produced under jam
conditions, which is why it earns its place here. Unpacked from `Ningriptzu Art.zip`;
folders lower-cased, `tilesheetv1mini.png` renamed to `tilesheet.png`. Pixels untouched.
Unused sub-folders (`Misc/`, `Riceball/`) were not vendored.

`ninja/kenneyninja.png` is the author's stated starting point, credited by them to
**Kenney** (<https://kenney.nl>, CC0). It is kept for provenance and is not used in any
lesson — note that it carries five colours, not four.

Unpacked from `2DRP_CCArt_Gameboy_Cave.tar.gz`; `LICENSE.TXT` kept as `license.md`.
Pixels untouched. This is the counterexample in Lesson 02: a cave that reads bright.

## armm1998-topdown/

**Gameboy Tileset** by **ArMM1998**
Licence: **CC0 1.0 Universal**
Source: <https://opengameart.org/content/gameboy-tileset>
Retrieved: 2026-09-10

The author's stated aim was "to emulate the Pokémon aesthetic". Top-down, four greys.
Used as the bright end of the top-down key ladder — the thing the mission is moving away
from. Pixels untouched; `generated/topdown-pokemon-like.png` is the same sheet with its
baked one-pixel dither background flood-filled to transparency.

8×8 top-down tiles in the bgb Game Boy palette. Part of the style kit. Pixels untouched.

16×24, four-directional, with idle / walk / run / push / attack / hurt, plus weapons, a
portrait and a title screen. Same bgb palette as stealthix's tiles, which is what makes
the two combine into one style. Unpacked and renamed to `knight-sheet.png`; pixels
untouched.

Note: the sheet carries **eight** stray orange pixels (`#d9680f`). The build script drops
them when cropping, because left in they register as a fifth shade and push the knight's
measured key from 2.33 to 3.20.

## generated/

Not original art. Every file in `generated/` is a **mechanical transformation** of the
CC0 art above, produced by `../build-examples.py`:

- `sprite-whole.png` — frame 0 of `kiira-gb-platformer/fluffy/idle-walk-strip5.png`,
  cropped, unmodified.
- `sprite-shade-N.png` — the same frame with three of its four shades flattened to a
  neutral, leaving shade *N* visible. No pixel was moved or invented; pixels were only
  recoloured to a single flat neutral.
- `topdown-pokemon-like.png` — ArMM1998's sheet with its baked dither background
  flood-filled to transparency from the sheet border. Art pixels untouched.
- `knight-down.png`, `knight-walk-block.png` — crops of Chasersgaming's sheet, with the
  eight stray orange pixels erased.
- `tile-floor.png`, `tile-wall.png`, `tile-void.png` — single 8×8 cells cut from
  stealthix's interior sheet, unmodified.
- `ground-bright.png`, `ground-grim.png` — earlier representative-ground crops, kept for
  the Lesson 02 measurements.

`measurements.json` is likewise generated — it is a count of the pixels in the art above.

The `key-shifter` widget in Lesson 02 recolours this art live in the browser. It also
only ever remaps existing shades onto other existing shades; it never adds a colour and
never moves a pixel.

16×24, four directions, drawn with three shades plus transparency. Unpacked from
`GB Ranger Files FREE.zip` (PNG set only; the BMP duplicates were not vendored).
Pixels untouched.

16×24, four directions, three shades plus transparency. Only the walk cycle was
vendored from `GB Kung Fu Man 4way.zip`. Pixels untouched.

## pebonius-gb-mini/

**gb mini pixel world** by **pebonius**
Licence: **CC0 1.0 Universal** — "you don't gotta credit, but you can link to this page

Source: <https://opengameart.org/content/gb-mini-pixel-world>
Retrieved: 2026-09-11

`pc-walk-{down,up,left,right}{1,2}.png` and `tileset.png`, unpacked from
`gb-mini-pixel-world.zip`; the 4× preview copies and GIFs were not vendored. 16×16,
top-down, bgb palette. These files ship **without transparency** — the sprite sits on a
flat Paper background — so the build script flood-fills Paper to transparent from the
border before measuring, exactly as it does for ArMM1998's dither. Paper *inside* the
drawing survives. Pixels untouched.

## generated/ — Lesson 05 additions

Also mechanical, also from `../build-examples.py`:

- `frame-{character}-{direction}.png` — one standing frame per direction, cropped to its
  bounding box (Chasersgaming's eight stray orange pixels erased; pebonius's flat
  background cleared).
- `proportion-{character}.png` — the down, up and side frames placed side by side with
  their feet on one line.
- `head-band-{character}.png` — the down frame with every row below the pinned head
  split recoloured to one flat neutral. The split row is a pinned constant in the script.
- `front-back-{character}.png` — the down and up silhouettes, bottom-centred on one
  canvas, and a third panel marking only the pixels that differ.
