AI Disclosure
AI was used during development. I started with Codex GPT-5.5 and completed the game with GPT-5.6-sol, using AI assistance for programming, including the puzzle generator and validation. AI-generated artwork was used for visual assets such as the journey trophies. AI also helped draft and translate this listing. The development work included checking for unique solutions, duplicates, similar puzzles, and uneven path distributions.
