Open Source JavaScript Games for ChromeOS

OriLauncher is a free and open source custom launcher for the popular game Minecraft designed to streamline the process of launching the game with a modern, user-friendly interface. Built using web and desktop technologies like Svelte, Electron, and Vite, it aims to provide a fast and responsive experience for players across multiple platforms including Windows, macOS, and Linux. The launcher enables users to switch quickly between different Minecraft environments (such as Vanilla, Forge, or Fabric) with just one click, eliminating manual setup steps. It also offers support for managing multiple user accounts, remembering both Microsoft and offline profiles to make logging in simpler and more fluid. Players have control over technical settings like RAM allocation and Java version selection directly within the launcher, allowing them to optimize performance for their system.

Blockly Games is a collection of educational games that teach core programming concepts using Google’s Blockly visual blocks. Each game introduces ideas like sequencing, loops, conditionals, functions, and variables through playful puzzles that gradually increase in difficulty. Under the hood, the block programs compile to JavaScript, giving learners a bridge from drag-and-drop logic to real code. The activities are self-contained and browser-based, requiring no installation, which makes them suitable for classrooms and workshops. Progression is scaffolded: earlier levels constrain the toolset, while later levels unlock more expressive blocks and optional textual views. The project’s emphasis on immediate visual feedback and forgiving iteration lowers the barrier for first-time programmers while still rewarding mastery.

Matter.js is a flexible 2D rigid body physics engine written in JavaScript, designed for use in web applications to simulate real-world physical interactions within the browser. It offers a comprehensive set of physics features like gravity, collisions, restitution (bounces), friction, sleeping bodies, and constraint systems that enable developers to build interacting objects with realistic motion. This engine can power everything from dynamic interactive animations and educational simulations to fully fledged physics-based games, and it works across major browsers and devices. Through modules such as Matter.Body, Matter.Composite, and Matter.Constraint, developers can create complex scenes with multiple bodies, jointed structures, and collision responses. Matter.js is popular in the web development community due to its simplicity, extensibility, and rich documentation, allowing both beginners and experienced programmers to leverage physics without deep expertise.

Tower Building Game is a small game project — likely implementing a classic “tower defense” or “tower-based” game — designed to showcase game-development fundamentals such as rendering, game logic, user interaction, and possibly simple physics or animations. As an open-source repository, tower_game aims not only to deliver a playable game, but also to serve as a learning resource or template: developers can inspect its code, understand how game loops, input handling, asset management, and state updates are organized. This makes it useful for programmers who are curious about games but don’t want to start from scratch. Because simple games often involve fewer dependencies and easier build processes than full-scale games, tower_game can be a good starting point for hobbyist developers, students learning programming or graphics, or for integration as a mini-game inside larger projects. Additionally, its open-source nature lets contributors fork and improve it.
