I've created a few computer games that you can play in your web browser. They were written in Java, which is no longer supported in modern browsers, but they can still be run using the  CheerpJ Applet Runner extension for Chrome or Edge. You need to install the extension, add it to your browser's toolbar, and enable it for my domain.
