Curvytron 2, I rewrote my browser party game, 10 years later
Hi everyone, french web dev here, About 10 years ago I did a little party game in the browser inspired by Achtung die Kurve genre, it reached HN (https://news.ycombinator.com/item?id=9494619) and everything went crazy, it's still largely played in open-spaces all over the world today. This past year, I've been working on a sequel: https://curvytron2.com is live. Same goal as the first one: challenge myself, perfect my skills, have fun and give back to the internet community the best way I know; by just putting a free little fun game out there. No ads, no tracking, no…
In plain words
Curvytron 2 is a free browser-based party game where players control curved lines in a competitive multiplayer arena, inspired by the classic Achtung die Kurve genre. Built by a French developer as a complete rewrite of the original game from a decade ago, it features improved 3D graphics, enhanced gameplay mechanics, and polished visual effects. Designed for groups playing together locally, the game contains no ads, tracking, or monetization.

Hi everyone, french web dev here, About 10 years ago I did a little party game in the browser inspired by Achtung die Kurve genre, it reached HN (https://news.ycombinator.com/item?id=9494619) and everything went crazy, it's still largely played in open-spaces all over the world today. This past year, I've been working on a sequel: https://curvytron2.com is live. Same goal as the first one: challenge myself, perfect my skills, have fun and give back to the internet community the best way I know; by just putting a free little fun game out there. No ads, no tracking, no business plan. A decade of professional web development and hours of GMTK have raised my expectations and this time I aimed for: - a good looking top-down 3D view with improved gameplay and real game juice: I learn Three.JS and WebGL for this project, worked on the camera movements, screen shake, sound design, gameplay feedback and I'm proud of the portal-like effect of the bonus that allows you to peak and cross over to the other side of the map. - a solid 100fps server simulation (in Go) serving clients with a really bandwidth efficient netcode (it's binary websocket instead of plain JSON and I open-sourced it: https://github.com/Tom32i/netcode). - Instant reconnection, at any time: I had this requirement from day one, in the first curvytron losing connexion meant dropping out of the game permanently. Not anymore. You can just refresh the page mid-game and keep playing, try it yourself. The game runs in any desktop and mobile browser and supports gamepads I've put up servers in US and Europe to offer a good ping to as much players as I can afford at the moment. I still maintain and host the first game to keep the original experience live. I'd love to get feedback from HN, and don't hesitate to stress-test the game of course! I'll be around to answer questions and discuss if you're interested. Cheers!

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

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!
