Flappy Bird is the top Apple App Store app right now. Although the mechanics are simple, it is fun and addicting. Since I had some time this weekend, I decided to try to implement some of its mechanics. It also gave me an opportunity to refresh some of my JavaScript and DOM knowledge, since I haven’t touched it for quite awhile.

It is really bare bones, having implemented mostly just collision generation and detection, simple rendering, and the basic physics necessary. Although the code is fairly neat for several hours’ work, it could do with a generous refactoring and should not be considered exemplary code, especially with respect to maintainability.
