Buried Treasure
What buried treasure awaits in this place?
Build
To build the project, run
yarn
node maze.js
node shell.js
Then to start it, host the files in outdir
with any webserver. The easiest way is
cd outdir
python3 -m http.server
And then navigate to http://localhost:8000
in your browser.
Solution
This is a fully client-side problem, but it employs some fun browser features. No spoilers until after testing.
