game-engines

Game engines are software frameworks for game development. Game engines do the heavy lifting for developers so they can focus on other aspects of game development.

I suggest adding a .gitattributes with some merge driver lines so that
script.js index.html main.css main.js options.js
are excluded from merge, and maybe adding a "how to" in the readme/docs on updating the engine.

And perhaps a bit about gulp and the addons you're using too.
