Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)

I recently brought Infocom's original UNIX z-machine source code back to life on modern systems. The modified source code, instructions on usage, a build of the z-machine, and examples of embedded game executables are available. There is also a detailed write-up about the state of the original source code, the porting process, and the invaluable role Justine Tunney's Cosmpolitan project played in bringing the Zork trilogy (and more) to Windows/Mac/Linux/bsd for arm/x86 machines over the course of a lazy Sunday.

Recently, I managed to recover some of my earliest work from the ZX Spectrum era from an old audio cassette. It is a mini-game, that I created as a teen, called "Atomix," written in BASIC with a mix of Z80 assembly — some of which I coded myself, while other parts were disassembled from existing games. I put the game in an modern emulator and recorded a screencast. See the video in my linkedin post: https://www.linkedin.com/feed/update/urn:li:activity:7288665...

My cousin and I love the Terraforming Mars board game. But we'd often get overly excited and knock our pieces off of our boards, losing track of our progress. So I digitised it. It comes with a few cool features like resource conversions (e.g. converting plants to greenery), production phase, offline, mobile-friendly and keeps track of the history using the browser history itself. Sharing this here in case there are any other TM fans that could also find some use in this :)

Earlier this year, we released our open-source game engine [0] built with Rust, WebAssembly, and WebGPU. Today, we’re happy to announce the Ambient platform, which brings web deployment, server hosting, and more to the runtime. With Ambient, you can make a game, deploy it to the browser in one command, share your URL and instantly play with others, no downloads or installs needed. Our WASM use is innovative; it is being used as both a sandboxed runtime for user code, and as a way to run the entire Ambient runtime in the browser. This, paired with our ECS data model, enables a highly modular…

_Vector Defense_ is a retro vector graphics style tower defense game (demo). This was a holiday "weekend" project. I wanted to recreate some of the fun I had in the past with https://en.wikipedia.org/wiki/GeoDefense and one other (Android?) game that may predate GeoDefense, but which was fixed grid and placement. Creation Details I "wrote" this in English. 99% of my development came from carefully articulated directions and requests from me to Gemini 3 (usually planning mode, in Antigravity IDE). Music is also AI generated via Suno.com, from my prompts. SFX are samples…
