LunaHana —
A Witch RPG Built by AI

Vibe CodingGame DesignLLM NPCsCreative AIHuman–AI CollaborationRPG

LunaHana is a female-perspective RPG witch game that I built independently over five months — from concept to art to development. It has been my childhood dream to create a majo experience focused on self-discovery rather than traditional battles.

“I wanted to push the limits of AI-assisted programming and test how far AI can go in creative workflows.”

The project was driven by my passion for exploring human–AI collaboration. The key innovation is the integration of LLM-based NPCs and AI-driven open-ended magical interactions that generate rich, branching storylines — essentially creating a living, breathing world where every player's experience can be unique.
