Test of Phaser.js game framework with a trivial flappy bird-like. With an octopus. And bonus objects. Woaw.
Also, a school project.
Clone or download the repo, and put it behind a web server, whichever you like. Phaser.js needs a webserver to load some contents by Ajax. If you access the site locally, you won't have any sounds available but AFAIK the rest should be fine.
