    I've been working on Athena Crisis for about two years, and full time for the past 9 months. The game is entirely built from scratch using React and CSS without a game engine. It runs anywhere, including the Steam Deck. You can even use a gamepad on the landing page to play! Previously the landing page had a video of the game but my goal was to always just put the actual game on the website. I merged the landing page into the game's monorepo, added the game's React components, and boom – the video was replaced with a playable version of Athena Crisis. Of course, the real game has tons more…

    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

    Hey hackers, OP here! I've been dipping in and out of this problem space for the last few years with many of my clients. Puck sits somewhere between an old-school WYSIWYG-powered CMS and headless one, allowing content teams to author content using real React components. Traditional CMS solutions were flexible but often resulted in page that completely broke the brand guidelines. Headless CMS solutions are a fantastic way of controlling brand by restricting UI changes to developers, but makes layout changes restrictive and slow as developers often need to get involved. Puck provides a visual…

    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…

    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…

    This is something that I've been working on on-and-off in my spare time for the last few years. I started in 2020 during Covid trying to do a Mount and Blade style map in UE4, and it grew from there until where it is now - I would just add a feature, then another, until it came together. Since the start of the year I've really been trying to polish it some more. I've got the full thing planned for a Q3 25 release.

    Hi HN! I’ve been building a 2D game using a custom engine I wrote from scratch – no Unity, no frameworks. It’s fully self-funded and will be released commercially on Steam. Engine source code (MIT): http://github.com/willtobyte/carimbo I’d love feedback on the gameplay, visuals, performance, or anything else. Thanks!
