    Hello HN! We're the team behind Epistemeland (https://epistemeland.com/), a platform dedicated to making learning fun and accessible. We've just released a prototype of a single player game that uses basic geometry. It is a fist, but an important step in creating our MMO game to revolutionize education. The game mechanics are simple but intriguing and naturally incorporated in the game process. We built it with UE5 and want to continue development. We'd love for you to try it out and give us your feedback, which we'll use to guide our next improvement cycle. Our goal is to…

    Hey HN! We built *lapisla*, a theorem proving platform designed to make formal proofs more open and collaborative. We developed a kernel, editor, proof registry, and platform ── all accessible directly in the browser. Why we built this: Existing theorem provers are powerful, but they often feel isolated and difficult to extend. Unlike modern programming languages, which thrive on package managers and shared libraries, theorem proving tools lack a seamless way to integrate others' work. lapisla aims to bridge this gap by: * Offering a verified public proof registry for sharing and discovering…

    It's like a mix between Picross (Nonograms) and Polyominoes. It's a minimalist puzzler which has no text, no tutorials (none required) and no ads set in a relaxing environment. App Store: https://itunes.apple.com/gb/app/shapeuku-shape-puzzle-game/i... Play Store: https://play.google.com/store/apps/details?id=com.dtbgames.s... I have a bulk load of Android promo codes to give away, so if you'd like one let me know! (Sorry iOS users, I have no free codes left!)

    A minimal "@ moving around a hardcoded map" implemented in a bunch of languages, some by me and some contributed by others. A slightly more interesting riff on the Hello World or 99 Bottles of Beer theme. More languages or improvements on existing ones would be nice :) There's a github repo at: https://github.com/nrkn/SimpleRL

    Launch day is here! This has been my passion project, to recreate Duolingo for chess! I always thought Duolingo had amazing "hooks" to help people learn new languages, so I implemented its spaced-repetition, reports and daily and weekly training reminders in a Chess learning platform for chess improvers! I built it in Meteor.js and React.js. I chose Meteor to be able to add Cordova in the future. The Caro-Kann course (for white) is completely free, if you guys want to try it. What do you folks think?
