KonsolScript and Game Engine
Free and Open Game Programming Language for Windows and GNU/Linux
KonsolScript is a free and open source, scripting language primarily intended for 2D games development. KonsolScript Development Team believes that the unavailability of games on GNU/Linux desktops is one of the major concerns why people keep using unauthorized copies of proprietary OS over GNU/Linux and that is something the Development Team is ought to address – we are doing our part to help promote GNU/Linux as a viable gaming platform for desktops both for Game Publishers and Gamers. The whole Game Development Kit is suitable for teaching 2D game programming. The end goal of this project is to have a common gaming platform for Windows, GNU/Linux, Mac OS, including mobile platforms like Android where any newbie can learn how to make his game/animation etc. A lot of work has been made and a lot more is to be done. It might need to hire programmers to make an engine for Android, and Mac OS, then some in-house testers for stability among these platform -

Ct.js
Ct.js is a desktop game engine that makes learning programming fun
ct.js makes learning programming fun and game development easy by its visual tools, good docs and flexible, modular library. It is free, open-source, and is loved by hobbyists, professionals, teachers, and their students. Bad tools hinder your performance. Ct.js is designed to be like a brush with which you create games, not to be an enemy you will fight with. ct.js bundles come with offline docs, tutorials, and editable examples and demos. The code editor highlights errors and provides documentation right while writing your code. ct.js is based on Pixi.js, works on WebGL and provides great performance in browsers and desktop environments. Modules add new powers, and when ct.js is not enough, you can add any JS code or library. A small stylized adventure with AI-powered sea battles, violent environment, and little puzzle sections. Join the voyage to save a colony from a deadly disease! -

Wheefun Ingeniously Retro Engine
Low-Level Game Engine for Retro Platforms
WFIRE is a low-level game engine which provides a portable library allowing for writing video games for multiple classic targets. Originally written for a game called the Crypts of Eldor, WFIRE aims to provide compatibility with a number of constrained environments, such as DOS and the Amiga. It also aims for "new-retro" computers such as the Commander X16 and the Neon816. Of course, modern operating environments such as Windows NT and GNU/Linux are also planned. WFIRE is meant to reduce the effort of writing your own game engine by providing a common framework for functions such as rendering, sound output, and display management. -

ZAPH
Tools and Z80 engine for creating adventure games. (RUST)
This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools.
