About MrPhil

Philip Ludington / MrPhil

I'm a game director in Austin, TX building Stellar Throne — a sci-fi 4X with rich exploration, competent AI opponents, and AI-assisted development. Weekly updates on solo dev, agentic coding, and building ambitious games with modern tools.

Currently Working On

I'm currently developing Stellar Throne, a sci-fi 4X that doesn't take tens of hours to play. I'm also building Changesmith, an AI-powered tool that turns your git history into polished release notes your customers will actually want to read. Crimson Crisis, a roguelike sci-fi action game that you can wishlist on Steam, is on the back burner.

Open Source Projects

I maintain a number of open source projects on GitHub, mostly focused on AI-assisted game development:

  • Klar — A programming language designed for Claude Code and AI-assisted development.
  • Kira — A functional programming language with explicit types and tracked effects, designed for AI code generation.
  • Agentite — A family of game engines built for AI agents, with variants in C, C3, Zig, Godot, and Klar.
  • Carbide — Hardened coding standards for AI-assisted development across C/C++, C3, Zig, and Unity.
  • Sanna — A specification language for AI-assisted development with formal verification and confidence tracking.
  • GameDevelopmentBenchmark — A benchmark suite for evaluating AI model capabilities in game development tasks.

Game Development Journey

I've been creating games and writing about game development since 2005. This site serves as a portfolio and blog where I share my experiences, projects, and thoughts on game design and development.

Built with Next.js, Tailwind CSS, and deployed on Vercel.
