    As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…

    It's free to play on steam, but you'll need a computer with a dedicated graphics card. I just released a new version after first releasing it 18 months ago. It's been a hard slog to scrounge time as it's not my day job but that's life. There's a ton of obvious improvements in the future (weather systems, temperature, varying rainfall, ice/snow, more biomes, more plate tectonics, lava, etc) but all suggestions/feedback is welcome.

    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…

    My background project for the last two years has been re-implementing my 2004 C++ shoot'em up game in TypeScript + WebGL, and it's finally done (just in time for the 20th anniversary!) Play the game online: https://nicollet.net/blog/darklaga/darklaga.html Technical article about the remake: https://nicollet.net/blog/darklaga/remake.html I have tested Firefox, Chrome and Edge on desktop and mobile (no access to a device capable of running Safari). It's amazing how much difference 20 years makes: the hardware is so much more powerful, the web…

    Most games have limits. You can only use preset features, need coding for customization & adding mods, require expensive extra devices. We wanted to remove those barriers. That’s why we are building space zero—a browser based 3D world powered by AI. We plan to build players can freely mix items to generate unexpected creations with unique properties and sounds. Also the world itself is dynamically generated, evolving endlessly. I uploaded a demo version I’ve been working on for the past month! I hope to get any feedbacks or comments :)

    Hey HN! What started off as a meme has turned into a passion project and I'm pretty excited about it. As the title suggests, I made a Rock, Paper, Scissors game in React. The twist is the perk shop that you can power yourself up upon wins. I have a Node web socket backend because it started off as just a PvP experience, but I wanted people to be able to play a solo mode. That's where the Roguelike comes in. I still have plenty of features to go! But for now, it's an endless Roguelike where after each round, you get to upgrade a shop perk to make your character stronger. I'd love to get some…
