A free and open source Japanese-style "bullet hell" (Danmaku) top-down shooter; a fangame of the Touhou Project series.

Original engine built with SDL, with 2 custom renderers (OpenGL 3.3 and SDL_GPU). Written in C (GNU C11), with tooling written in Python. Runs on any modern desktop OS and in the browser (via Emscripten).

• Wrote most of the engine, including but not limited to the renderer, audio, virtual filesystem, replay, live reloading, and threaded asset loading subsystems.

• Designed and implemented a coroutine-based system for asynchronous programming of game logic and stages.

• Designed and implemented a lot of the gameplay mechanics, stages, bullet patterns, and special effects.

A small, decently portable C11 library that implements asymmetric stackful coroutines (similar to Lua's coroutines, but for native code). Supports many operating systems and CPU architectures. Modular design, can use boost.context assembly routines, POSIX ucontext, Windows fibers, longjmp, Emscripten fibers, etc.

Designed for use in Taisei Project, but is general enough to be useful elsewhere.

An LLVM-based suite of tools for compiling C/C++ applications to WebAssembly, as well as a runtime to run them in the browser.

• Designed and implemented the Fibers API and runtime, a low-level context-switching primitive similar to POSIX ucontext, based on Asyncify.

• Found and fixed various bugs in the runtime.

A declarative build system written in Python, meant to be as fast and user-friendly as possible.

Taisei Project uses Meson extensively.

• I often test unstable revisions; identify, report, and fix bugs and regressions.

• Proposed and implemented some minor features for my project's needs.

• I maintain custom Meson build definitions for most of Taisei Project's dependencies, including SDL2, Basis Universal, SPIRV-Tools, glslang, shaderc, SPIRV-Cross, libpng, libwebp, Freetype, libzip, zlib, ogg, opus, opusfile

A widely used platfrom abstraction library for games and other multimedia applications.

• Participated in the development of SDL_GPU, the new GPU abstraction subsystem in SDL3:

  • Wrote an SDL_Render driver using the new GPU API.

  • Found and fixed some API deficiencies prior to stabilization.

  • Found and fixed various implementation bugs.

  • Helped with testing and benchmarking as an early adopter of the API via Taisei Project.

  • Helped with establishing the supported feature set.

• Contributed a performant hashtable implementation.

• Submitted various bugfixes.

A formerly popular multi-feature mod for Nexuiz, a defunct open source first-person arena shooter game. Features new game types, bug fixes, server administration tools, updated graphics, Xonotic backports, and more. Written in a dialect of QuakeC, an interpreted language for Quake 1-based engines.

A fork of the DarkPlaces engine which powers Nexuiz and Xonotic. Features RocketMinsta-specific extensions and compatibility fixes.

A fork of fteqcc, a QuakeC compiler, used to compile the RocketMinsta source code. Features various language extensions and fixes.

A beatmania-style rhythm game written in Python with a pygame frontend. Can load osu!mania beatmaps.
