Onirim
Onirim is a solo board game with simple rules. I'm using the rules here
This is an implementation using the Elm programming language.
To get up and running, npm install and npm start is all that is needed to
start a dev server with the game running at http://localhost:1234
If you want to hack on this, Elm and elm-format will get installed with the npm install, and I use VSCode with the Elm plugin, which should be all you need.
