# Wu Wei: credits and licences

All third-party art below was recoloured into the Wu Wei GBA palette (RGB555, at most 15 colours plus transparency per sprite). Some of it was also edited or extended: the hero's guard, kneel, jump and fall frames are new, and backgrounds were split into props and re-tinted per time of day. Licence terms checked on 2026-10-04.

## Original work in this project

These were all built for Wu Wei, mostly in `tools/art/*.py`:
- The palette and the day/night (yin/yang) swap table.
- Sky gradients, sun and the taiji moon.
- Bamboo forests, ground strips, platforms, torii, lantern, talisman gates and the sign scroll.
- Every HUD and FX sprite.
- The hero's extra frames: the whole unarmed Master set (idle, run, jump/apex/fall, midair roll, guard, air guard, deflect, air deflect, gather, release, dash, the 3-pose execution, settle, hurt, kneel). These were made in Pixel Studio from the Mattz Art base. See `art/studio/` for every job's prompt and result.
- All synthesised audio.
- Game code.
