Build me a local party game app where your phone becomes the controller and the computer runs the game.

I want people on the same Wi Fi to open a QR code on the main screen, join from their phone browser with no app, and use motion plus buttons to control simple games. The main computer should show a menu to pick games, manage up to four phones, and keep everything feeling smooth and responsive. Please include a few different mini games like racing, fruit slicing, a flying shooter, a target shooting game, and a drawing game.

It should work in the browser, support motion controls over HTTPS, and make it easy to start on a laptop or desktop with a local server. If you need to look up current docs online for any browser or motion sensor details, go ahead. Make it feel polished, fun, and easy to launch from one command.
