Giommy the Dino
A small game in one file. No install, no app store.
Space bar, click or tap to jump the rocks. Every five rocks a new level, and Giommy runs faster.
One HTML file. Double-click it and it opens in your browser. Type your name in the game, or open it with a text editor and change the two names at the top: it becomes your kid's game. The world record lives only here on the site.
