My first PICO-8 project, based on the excellent tutorial work of MBoffin! A Flappy Bird-esque game of surviving as long as you can.

　　The entire game can be played with just the Up Arrow; players may also reset at any time using X.

　　Updated 11/18/2017:

　　Gameplay-related:

　　Rebalanced gravity and jump strength to make play more dynamic.Decreased collision size on the bottom of the UFO; it now feels better and is more lenient.Slightly reduced the foreground parallax's intrusion over the midground to decrease the chances of having "blind" jumps or sequences.

　　Quality of Life:

　　Added a border to the screen area.Added a flickering color to the score text every 1,000 points to mark progress.Added lighting effects at the edges of the screen: darker in the deeper cave, lighter towards the exit.Added a dedicated title screen with new title and other info.Minor revamp to the game over screen.Updated music. It's still the same elements but in a slightly less obnoxious loop.Updated the desktop icon for the downloadable executables.Separated the Windows/Mac/Linux downloads for user convenience.
