A solo developer building an ocean ship game with Claude Opus 5.5 has shared his workflow and costs, alongside a free playable demo.
→ He runs a separate Claude session for each game system and talks only to a 'manager' session that messages the rest
→ A decisions.md file tags every choice as [USER] or [AI], with user decisions always taking priority
→ He uses Blender MCP and TripoAI for 3D models, Godot MCP for the engine, and Codex when Claude limits run out
→ He says the project cost about $800 over two months, including $600 for Claude Max
