24 alternatives to Loodfun

I originally built Loodfun to make playable wedding/birthday invitations, little escape room style games you send to guests instead of a boring card. It didnt work, but somewhere along the way i pivoted towards an interesting problem which is learning/training. Every company or school has onboarding pdfs or slides and also learning courses/material, and people skim once and forget (i did that many times). so i shifted focus to that task, you paste in a course link, a pdf file, or even a wikip page, and it generates an actual playable 3D game with different maps/camera…

    Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!

    Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

    Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

    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!

    Hi HN! 2d spritesheets for game development are often distributed as a PNG image, sometimes with a separate JSON or XML metadata document describing the layout, including any animation sequences within the sheet. Sometimes there is no metadata document and you have to work it out and manually write custom code to chop up the spritesheet and reference the sprites you want. I think it would be good if it became standard practice to distribute spritesheet PNGs with the metadata inline inside a PNG "chunk" so the whole thing is self-contained. That way artists can just distribute one file, and…

    Took a break from the falling sand simulation blog posts this week to work on another small project. It's a little pixel world generator- each time you visit, you'll see a new little world. I really like this stuff and had a blast building it yesterday!

    I learned Pixel Art design on Coursera and built a pixel art game for my wedding's save the date using React. The game is on "endless runner" style and our guests have to jump over the typical animals of the island of Florianopolis (where the wedding took place) and gather the two rings in order to find out the wedding date. Play it and try to "Save the Date".

    Hey, I've shared this game while it was still a work in progress in one of the Tell HN threads. I was pleasantly surprised that a lot of people tried it, and I got some positive feedback and constructive criticism. Anyway, I found a gamedev library I really like - Kaplay [1]. What I like about it is that easy things are easy. Meaning I could have fun building the game without learning (or fighting) a new tool. I always wanted to make games, but this is the first one I actually did. And I have to tell you - game development sparks joy! It combines so many things (game design, programming,…

    I've been working for a while on trying to curate a game that has the emergence of procedurally generated computer games but that can be played with only pen and paper. Here I present the best version I've been able to come up with that is simple and emergent. I've really enjoyed being able to engage with this sort of game while not feeling like my brain in rotting. I recon my numeracy improves while playing it.

    So, me (dev) and my friend (designer) have been building a website/mobile app to help users manage their game library (think MyAnimeList, but games) for a little over a year. We launched with a very basic set of features, and have been slowing expanding since then. All the code is open source, and most of the things we implemented were direct feedback from users (e.g. being able to import games from Steam/PSN, and the Posts feature). We don't show ads or have any kind of subscription. This is just a hobby project. Any feedback would be greatly appreciated, as honestly the hardest…

    I'm one of the developers of Spark, a new open-source 3D Gaussian Splatting renderer (sparkjs.dev). While developing Spark, we built a WebXR demo that lets you experience a stream of 3D AI-generated worlds from "inside". These worlds were made by World Labs from text+image prompts last year, and I think it's really cool to imagine what's going to be possible in the near future! If you have a Quest 3 or Vision Pro, open up lofiworlds.ai in the web browser and make sure to enable hand tracking so you can "touch" the 3D Gaussians :). Tap your wrists together to toggle spotlight mode. The demo…

    I tried to train text to video and image to video models to generate 2D game animations. I used public game animation data and 3D mixamo model rendered animations to train the animation generation models. I'm open sourcing the model, training data, training code and data generation code. More technical details can be found in my blog (https://www.gavinliblog.com/posts/godmodeanimation).

    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!

    I wanted to make a fun, wholesome experience for our wedding website. Before long, it had turned into Loft Day: a point-and-click browser game with ten rooms, a party, a road trip, and a lot of smaller games, apps, and hidden interactions. Most of it lives in one 8.8 MB HTML file—roughly 138,000 lines of HTML, SVG, CSS, and JavaScript, with no framework or build step. It also runs a few real runtimes inside the game, including Python through Pyodide, a small Linux system through v86, and, of course, classic shooter games. I developed it over about a month and 5,700 commits, working with…

    Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer games work, which is why we decided to work on this project. Our goal was to gain a deep understanding of how different players can share the same 3D space, which is why we wrote our own tiny game engine instead of using something like Unity. We wrote the engine using C++ and OpenGL, and we then compiled it to WebAssembly using Emscripten so that it would run effortlessly on web browsers. We are really excited about…

    Hello HN! I’m excited to share PixelDojo.ai, an all-in-one generative AI studio for creators. I built PixelDojo to be a one-stop platform where you can generate images, create short videos, and even train custom AI models (LoRA fine-tunes) from your own images. The idea came about because the AI creative process felt fragmented. 10 months ago I set off on a journey to create the ultimate AI playground. A place where cutting-edge image-generation tools are easily accessible. My goal was to bring all the latest AI creativity tools under one roof so that anyone, even a “noob” with no prior…

    Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you…

    It took me about a week to vibe code this 3D game engine with Opus 4.6 that I intend to use as a replacement for Three.js and React Three Fiber in my browser MMORPG, Mana Blade. I was not expecting to be able to reach that point so easily, but pretty much every feature took somewhere between 30 minutes and 1 hour - 1 to 3 prompts on average. It is vibe-coded in the sense that I haven't looked at the code, but I am very careful with my prompts and constantly have Claude reviewing the codebase, looking for performance and code quality improvements. It can reach 2000 draw calls on recent…

    Hey HN, I made https://linkians.com which is a game where all the action and state is contained in the url. The game involves taking care of little pets (emojis) that live in your url bar. Kind of like tamagotchi or sims. Feed them, play with them, and watch out for enemies! There's no server, just emojis in the url and client-side logic. Any linkians url using the supported emojis is a valid game state so you can save your game, or type out your own url and send it to a friend. I'd appreciate any feedback.

    Happy Halloween! Instead of going to a Halloween party this year, my wife and I decided to run a tiny Hackathon and built this little retro choose-your-own-adventure to pay tribute to a popular series of yesteryear. Try and escape! Also pumpkin mode!! We made liberal use of ChatGPT for code, DALLE3/Midjourney for images, but did most of the storyboarding/writing ourselves because we couldn't stand the style of GPT4/Claude.

    My wife and I recently submitted to a mobile game jam on Newgrounds (yes, it's still around). What started as a question of whether we could do it somehow morphed into whether we could do without so many of the seemingly needless complications rampant in our respective industries. My wife thus did all the art as traditional frame-by-frame animation (no puppets or tweening) and I preceded without a game engine. I did use a pre-processor that gives JS a Lisp syntax (Parenscript), because C-syntax is gross. We hope the end result, while definitely of small scope, will serve to inspire some…

Anybody on the web can submit a prompt, and up/downvote other prompts, and every ten minutes the top one gets submitted to Claude! Anyway, I think it works?
