Thank you for the suggestion, but I don’t have any plans on adding more features to the game or modifying it beyond what’s needed to work with other common WordPress plugins, because I want to keep the plugin lightweight and fast.
The game is a JavaScript file forked from the ‘T-Rex runner’ game in Chromium (Google Chrome) https://cs.chromium.org/chromium/src/components/neterror/resources/offline.js Since it was designed to run in the “offline” screen of Chrome, it’s made to be very lightweight and have no persistent memory for options or high scores. The plugin version of this game was made with a similar goal. It is used as a shortcode, makes no use of the WordPress database or user sessions, and is fully cacheable.
However, there are some interesting forks of the same JavaScript on github you may want to check out if you wanted to take on that project yourself. https://github.com/wayou/t-rex-runner Those are open to fork and so is this plugin. You’re free to make any modification you wish.
