One-Two-Three Quarkus

This is a fun version of the ‘freeze or die’ game, where each phone represented a player on screen. By shaking your phone, you can advance your player towards the finish line… provided you don’t ‘die’ along the way!

It is dedicated to explaining how Quarkus simplifies the process of creating such an interactive and scalable game. The extensions involved are:

• Web Bundler
• Qute
• Renarde
• Playwright for testing.
