Gillespie explains in the video that he created a JavaScript Snake game 15 years ago. His goal was to shrink it down to the point where the game uses the individual subpixels of a monitor.

サーニ氏の息子が作ったゲームは「THE GAMEY GAME」というタイトルで、GeminiにJavaScriptの書き方を聞きながら作られたとのこと。

THE GAMEY GAME is a game where you can play against monsters, and the initial screen has a row of buttons that allow you to select your opponent. Click 'flying snake' to try it out.
