The Cave-In At Erk'Lak

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.
