    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…

    Hi, I wanted to share a simple game I wrote. It's a sliding pieces puzzle like many others. I have focused a lot on making the experience smooth and minimalistic and the levels being challenging in a way a sudoku or chess puzzles could be. I had no prior knowledge of game development and while it feels like someone competent could build this game in a week I spent over two years and hundreds of hours to bring this game to life. My journey went through: - thinking it will be a PC game - being overwhelmed by the amount of different game frameworks - hiring an indie dev to bootstrap the game in…

    I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as the platform overall. All of the code is available at https://github.com/homegamesio

    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!

    This is a game I wish I had as a kid learning programming. The concept of it is fairly similar to other coding games like Screeps, but instead of a complex world with intricate mechanics, Yare is a lot more minimal and approachable with quick 1v1 <3 min matches. It's purely a passion project with no monetization aspirations. And it's open source: https:&#x2F;&#x2F;github.com&#x2F;riesvile&#x2F;yare The first version 'launched' several years ago and I got some good feedback here: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=27365961 that I iterated on. The latest overhaul is a result…
