This is a game that I started to build many years ago. Before Node.js existed.
The game itself was basically a Zork-style text adventure.
The original game was built using the JS engine from Mozilla. I compiled the engine and provide a couple of native functions so that the JS could consume input and emit output and the rest was done inside the JS context.
It was cool, but I never pursued it.
I dug it out recently, and spent about 1 hour converting it to use Node.js instead of the Mozilla engine.
This is the result of that conversion.
I'm still hoping to flesh it out some more.
