Kapendev/parin

A D-language 2D engine positioned between raylib and Godot — Parin is a code-driven 2D engine for D, offering more structure than a bare library like raylib but far less overhead than a full engine like Godot. Built on the Joka utility library, it bundles physics, dialogue, animation, and tile map tools, with Web, Windows, Linux and macOS support.

A delightfully simple 2D game engine.

kitao/playload

Pixel Games Compressed Into a Shareable URL, No Server Needed — Playload is a tiny JavaScript game engine that packs an entire retro, pixel-art game with chiptune sound into a URL, so you can share a playable game by just sending a link. It ships with a built-in code editor, API cheat sheets, emoji-based 8x8 pixel art, and runnable examples, making it appealing to creative coders and gamedev hobbyists who want instant, zero-install sharing.
