It compiles to native code via LLVM, features arena-based memory management as a first-class language feature, self-hosts, and runs a full port of DOOM (56,000+ lines). The project was also an experiment in AI-directed development: the author acted as architect, setting acceptance criteria and tests, while an AI coding agent handled all implementation. The DOOM port validates correctness through bit-for-bit identical fixed-point simulation replay against the reference C build. The project is considered complete with no roadmap planned. ## Full article daily.dev links to this article rather than hosting it.
