I went to the Micro Museum in Ramsgate. Although most of the old computers there were being used for games, I spotted the packaging for Acornsoft Forth, for the Electron, in a display case, and that got me wondering about Forth.

To keep myself sane, IO is via the browser, with Typescript rendering the game state to an HTML Canvas. The game logic, though, is all Forth, run via WebAssembly using WAForth
We have a snake that moves around a board.
$ npm start runs it. Or it's on github pages -- here
