A flappy bird clone that be played multiplayer. (Well, technically it's more similar to the helicopter game.)
It's run by Express.js, p5.js, with socket.io. The code is based off Daniel Shiffman's course here.
To install:
$ git clone https://github.com/grgp/p5-flappy-multiplayer.git # or clone your own fork
$ cd p5-flappy-multiplayer
$ npm install
$ npm start
Your app should now be running on localhost:5000.
