Neon Go Stop

Copyright 2026 Neon Go Stop project owners. All rights reserved.

The game, website, source code, card presentation, characters, interface, writing, and project-created artwork are proprietary unless a third-party notice below says otherwise. The repository is not offered under an open-source license.

Art and audio provenance

The current alpha card faces, card backs, table, avatar, pet, cinematic, and interface artwork were created or generated specifically during development of Neon Go Stop and are not represented as historical hanafuda reproductions. The card system is inspired by the traditional structure and natural motifs of hanafuda.

The current alpha uses project-authored synthesized and programmatic audio cues rather than shipped third-party music or sample libraries.

Commercial release checkpoint

The current card-art README identifies portions of the deck as concept or development art. The release owner must complete the asset-by-asset provenance attestation and final-art approval before a commercial release candidate is signed.
