/**
* Changelog:
* - Added game over screen
* - Flappy bird can now fly up above the screen but will still die to obstacles
* - Flappy bird can no longer go underground
* - Added alternate control for "flapping". Which would be the space key.
* - Flappy bird now flaps a whole pixel lower.
*
* TODO: Save your best score
* TODO: Add scores page
