Hypersplit – Like Infinite Craft but in reverse
Hypersplit is like Neal's Infinite Craft but turned upside down. Instead of crafting your way up from the four elements, you start big and go small, down to quarks. It's using GPT-4 to split the words, but a big difference from Infinite Craft is that I can precalculate the possible paths since they are limited (sooner or later you hit a quark or a loop). This means that I can ship it with the whole dictionary locally instead of hitting an LLM every split. While it started with just the splitting, I quickly got the urge to split things faster... which turned the app into the incremental…

In plain words
Hypersplit is a reverse version of Infinite Craft where players start with large words and repeatedly split them into smaller components, eventually reaching fundamental "quarks." Using GPT-4 to determine splits, the game pre-calculates all possible decomposition paths and stores them locally, eliminating the need for constant API calls. The app evolved into an incremental clicker where players can accelerate splitting speed. Built entirely with emojis and CSS, it offers a text-based experience with chain reactions and progression mechanics.

I made a Doom-like game fit inside a QR code2025 · github.com · ▲531I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…
A Marble Madness-inspired WebGL game we built for Netlify2024 · 5-million-devs.netlify.com · ▲616Hello 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…
Hypertune2025 · hypertune.com · ▲260Hey HN! I'm Miraan, the founder at Hypertune, and I'm excited to be posting this on HN. Hypertune lets you make your code configurable to let teammates like PMs and marketers quickly change feature flags, in-app copy, pricing plans, etc. It's like a CMS but instead of only letting you set static content, you can insert arbitrary logic from the UI, including A/B tests and ML "loops". I previously built a landing page optimization tool that let marketers define variants of their headline, CTA, cover image, etc, then used a genetic algorithm to find the best combination of them. They used…
