What the developer says
Music from Old Fairy Tales The music was inspired by reading old, well-known fairy tales, which I have rewritten and summarized in verse. With the help of AI (partly through singing and refining with AI) and post-production in Audacity, I was able to develop new songs from them.

| Steam disclosure | AI content disclosed |
| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure states AI assisted with singing and refining songs, so some shipped audio is AI-involved. The game is hand-drawn and the developer has only one release, with no sign of volume production. AI use is limited to music, not core gameplay. Against: Only 3 reviews long after release, but the developer has just one game, so this doesn't indicate mass production. |
