I made a Mario Galaxy game with Claude Code and Three.js in 53 days

What it does

Experience this Mario Galaxy-inspired 3D web platformer as you run around planets and play on letters from the Mario Bros. logo.

In the maker’s words, at launch

I'm the developer. Happy to share the process and learnings. Architecture: - Custom SoA ECS for cache-friendly iteration, zero allocations in hot loops. Benchmarked against bitECS/miniplex. - Process manager inspired by Game Code Complete's but data-oriented so processes are pure data, systems contain the logic.…

  My platforming game written in C 892023 · zamfofex.neocities.org · ▲127

  I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

  made a html5 game, polished it many many times2011 · hotbazooka.com · ▲211

  hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

  I made a puzzle game with Three.js2023 · thomasfriday.com · ▲82

  A while ago I discovered three.js, a JavaScript library to manipulate 3D objects. It looked really interesting, but I had no real need for it... To change that I recently challenged myself to make one 3D web game per month with three.js. And I just release game #2, a puzzle game called Cuboid, and you can try it here: https://www.thomasfriday.com/cuboid/ Please let me know if you have any questions or feedback. Thanks!

  Exponentile – A match 3 game mixed with 20482024 · bellika.dk · ▲54

  Hi HN, I made this small game in my spare time. It's quite addictive, I spent a lot of hours playing instead of polishing it. My own highscore is 96,792. Source code is at https://github.com/MikeBellika/tile-game. It's made with react, tailwind, and framer motion. Hope you enjoy!

  A small browser game (PC only) built with Phaser 32025 · cubic-zombies.pages.dev · ▲9

  Hi HN! This is my first game — something I’ve always wanted to do. It’s a small browser game built with Phaser 3, React, and the phaser template (https://github.com/phaserjs/template-react-ts/). I made it in 2 days (like 8 hours in total real time) using gemini-cli. About 90% of the code was generated with AI, but I learned a lot by making fine tweaks. It only works on PC since it’s a typical WASD + R (reload) shooter. I’d love feedback on: - Gameplay (is it fun, too hard?) - Ideas for new features Thanks in advance! ps: I used cubes as a prototype, but now I kind of…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
