A CLI text adventure(?) sandbox(?) thing(?) written in Lua that I've been working on for a couple days. You'll need a Lua interpreter to play it. Tested in 5.2.4 but might work in other versions.
I've also set it up on repl.it so you can try it out online.
I've put the code under the Unlicense. Feel free to share, modify, whatever you feel like. If you think you can take this further, that's great!
