If you can't wait for Flappy Bird to come to Windows Phone, give Squishy Bird a try. It's an HTML5 version of the game with a slight twist.

All joking aside, I'm posting this because I think it's genuinely interesting how far the HTML5 abilities of Windows Phone have improved. They still have a long way to go, and still haven't made file uploads possible, but IE is getting better each version, and while it's against Microsoft's best interests for people to make HTML5 apps instead of native ones, the overall experience of mobile device is greatly improved when the web browser has seamless support across websites. At least that's my opinion.

Enjoy the Squishy Bird.
