Rewtro is a weird retro game engine inspired by fantasy consoles and code golf that runs games encoded in a very small amount of data (2kb/3kb). This way is possible to share games using exoteric and usually data inefficient ways: i.e. sticking some PWA magic and a QR-Code reader to the engine I've made a fake gaming console for mobile devices. Games are coded using JSON structures. Includes tools for more easily building such games.
